Our farm is in San Ramón, Matagalpa, Nicaragua and we face many of the same challenges that you describe. I often joke that you could play a professional basketball game on our hard ground, and it would be competitive. Like you, we also are in a very severe drought. One thing that people do not understand is that you can plant cover crops and do Permaculture chop and drop, etc. but none of that material will break down and potentially add organic matter to the soil without rain. It also takes a good amount of water to make compost. But when water is scarce, organic matter from cover crops and other efforts does not break down with microorganisms. Instead, it breaks down through a different pathway by the sun and much of the carbon enters the atmosphere instead of the soil. Water is a major limiting factor to increasing SOM. I will be very interested to learn what things you are doing to increase SOM, including what efforts you are engaged in to increase water availability.
Thank you for sharing and confirming our experience. We are using Principles, Systems, and Tools to achieve these results. It is holistic in nature, but it is based on our "principles of regenerative agronomy"... video link shared soon... In short if we adhere to the 5 principles of regenerative agriculture including soil cover, living roots, crop variation, minimal disturbance, and inclusion of livestock we will set the stage. What we are finding to accelerate the increase in SOM and soil/crop health is to add labile, or "caloric" carbon sources with nitrogen applications and the addition of beneficial microbes. Now this is not "new" to most any of us, but I think often the rates are not high enough of either to reach critical mass. The number on carbon we are seeing as a good starting point is around .6 liters/ unit of N applied. When Im talking about the carbon source, ours is a very concentrated blend of molasses, fish, soy, corn steep etc blended with bio stimulants like kelp, pyroligneous acid etc. We try to create the most concentrated liquid with the most carbon sources possible in a "suspended" liquid to be applied with other sources of NPK etc. Hope this helps. We will be doing follow up videos and we will include more detail and examples.
How are you measuring determinating water/nutrient availability. Instrumentation/yields?? Using several labs analyses. I not a plant scientist but simply a food technologist reared on a dirt farm. Gotta run for now.
The 1st step forward is to acknowledge what has been done right, making a rapid 5 billion increase in global population possible. The next thing is to start moving forward as one. I’m certified organic, but I’m a farmer 1st. I partner with conventional operators, other dairies, farmer feeders, to make it possible to achieve high fertility. Marketable cattle are hard on dual purpose acres, I need to maintain the tonnage in animal units, but ship out animals as they grow, keeping the needle in the right spot. I’m a huge believer in grass finished beef, but I don’t have a market for enough animals to fertilize my operation. The genetics are sale proof outside of a small circle. If everyone did what I’m doing, their isn’t enough cover crop seed, not enough cattle, then their is the dilemma of what would we do with all the cattle? Basically, I’m an all the above guy.
In morocco , FertiDol can be quite effective in managing hydric stress in plants. Its composition, which includes Calcium and Magnesium, helps improve soil structure and water retention, making it easier for plants to access water during dry periods. This can be particularly beneficial for crops that are sensitive to water stress. "FertiDol" moroccan fertilizer.
I used to be very into taking care of my lawn and would do testing every year. The year that I was applying synthetic nitrogen as well as humates and kelp was the year my OM went from 3% to 4%.
i would suggest not to use any synthetic things, and just cover you ground with organic matter, compost is good for fertility and introduce microbes to your soil but those microbes need food and living space to thrive and grow and multiply, un other words 4 inches for the least of mulch mostly wood chips, make sure the wood chips are not uniform in size, you need it to be all of different sizes, some or small as powder, some or sizes of small rocks, like im just trying to say keep the sizes of the wood chip diverse and youll be good, always add this material to yur soil and never leave it uncovered, youll be socked year after year by the results you get, never disturb the soil, the microbes living in it will handle everything all you need to do is feed it, but giving it synthetic things chemical things, you are killing those living organisms, just watch Back to Eden Gardening documentaries and tours and youll learn all you need to know
Yes. This method has shown great success... but many producers farming on multi thousand acre farms are looking for solutions to achieve this without applying 4" of wood mulch. There was a reported 157,736,800 arable acres in the USA alone in 2021... the amount of mulch needed to cover those acres would be approximately 84,820,211,830 cubic yards and would require the harvesting of Approximately 84.82 billion trees just to cover the soil...... Im not sure what eden would look like if we had that kind of deforestation... just saying. The carbon sources we use to accompany our synthetic nitrogen sources which are derived from atmosphere are all by-products of other industries like fishing, sugar cane production, and ethanol. Again, thanks for watching and for your input. The "back to eden" method is wonderful and displays the power of keeping the soil covered and proper carbon cycling. I would say we use cover crops and stubble retention in large scale agriculture to accomplish this.
Thank you very much🙏🏾This was extremely informative. I find it helpful as here in Arizona. We have many similar environmental issues you describe in this video regarding your soils in Zambia. I’ve been growing wheat for several winters here, amp grazing cattle in the winter on the wheat, and in summer using a Sorghum-Sudan based mix. Our wheat yields have been dropping for the past few years. We’re trying to stick to regenerative-organic principles as much as possible, and are planning to put in row crop blackeye peas, to bring nitrogen into the system and expand our agricultural products. I was originally thinking to use mechanical cultivation as we do have a lot of weed issues, including prolific Johnson grass… however, after listening to this video, and the priority put on keeping cover on the soil, I’m questioning if strip-till might be a better option…? Do you have any thoughts on this?
Thanks very much! Glad to have helped. I would say that anytime you can accomplish what is needed and still refrain from tillage we should. Tillage is a powerful tool and should be used when appropriate, but we try to use it when it is there is no other tool that can do that task. If you can to strip till over full width I think that's best. Keeping that soil covered is 100% essential. It is the #1 step in our regenerative principles.
Very interesting discussion, have a look at your molasis under the scope, it already has yeasts in it, it's effectively concentrated plant sap, what could be better for plants!
The KEY CARBON SOURCE for Soil Regenetation... is Atmospheric CO2.... producing EXCESS Sugars and Lipids in the plants...To feed Soil Microorganisms. If you're not doing anything to OPTIMIZE PHOTOSYNTHESIS (i.e. by providing timely optimized plant nutrition... like the Consultants at Advancing Eco Agriculture INSISTS is required) you're not going to provode the best food for Microorganisms (abundant plant exudates in the Rhyzosphere)... Compost has value, but NOT CLOSE to abundant Root Exudates.... required to FEED THE RIGHT ORGANISMS... around the roots... the soil biology. You ALSO MUST provide proper SOIL PHYSICS... Compaction is a killer (tillage &/or Cover Plants)....and Water Retention in the Soil are key limiting factors.

I have used several soil test labs. Tissue test labs, seem like they aren't geared to test/recommend building soils useing the practices that you recommend. Ive been turning 8.7PH dirt into soil in arid Arizona with some of these regenerative practices, now ive started compost teas, worm bins, charcoal, molasses, and its changed. Which labs are geared to natural recommendations.
There are many good labs. We have used International Ag Labs often. We are also starting to use the soil test done at Apical labs to work on correlation between soil and our sap tests. The test mentioned in this video were done by Brookside laboratory. You can try the Haney test. Many regard this highly. We have yet to see it “working” in our western soils or in our African soils… we are still playing with it as many highly regard it for Regen soil building. Stay tuned as we learn. Thanks for your comment!
Not too many seem to understand how much carbon is in the SOM in 6" soil or 2 million lbs of soil. 1% is 16,000 lbs of Carbon per acre. Half life mineralization is taking out carbon also. A cover crop adds just hundreds of lbs, a small amount!
23 years no till, cover crops, and organic, with livestock on the land. Started out at 5-5.5% SOM on the home farm, which is pretty high. The guy I bought out was way ahead of his time. No tilling in the 70’s, and did some cover crops during 80’s and 90’s. It’s a tad over 10% now. SOM is not a silver bullet, it’s one factor. I have newer ground that is in the 2’s, and it does really well after just a few years of conservation practices. It soaks up water, is really mellow.
For over 20 years, Gary Zimmer has been convinced and taught to always add any source of nitrogen WITH active carbon sources so that the soil microbes do not mineralize the SOM/C to make use of the added nitrogen.
One of the key difference in this model compared to what Zimmer recommends is avoiding tillage completely. The difference is massive from the one filed we used light tillage on to the one we didn’t. Tillage is extremely expense in terms of soil OM burned off in our climate.
Depends on your region I guess. In the north I've built up SOM from 2% to 7% using only N and minerals within 5 years. Never took anything substantial "off" the field though...also put about 5 bu. of corn seed in as a cover crop each year on the 1/2 acre. Guess that accounts for some carbon but the majority of carbon was grown on site.
You think combining a humic substance with synthetic n is as good as manure? Definitely lacking the biology of ruminant manure, but perhaps like poultry manure.....
No. The ruminant manure is the high bar… we just do all we can to replicate it to those where manure isn’t economically feasible. Not to mention the numbers get pretty wild if you try to fertilize all the cultivate acres in the world with manure. We can do it but we all would need to eat a lot more red meat… many would see that as a positive though… what’s better than fresh beef off the veld?!
Herbicide to terminate the cover crop? Why not use a crimper or a sickle bade? I like what you guys are saying otherwise. good soil health or everyone. Tropical and subtropical soils sure don't want to keep organic matter, they want to cycle it as fast as possible. "Tools not systems, the systems come later." well said. I occasionally watch Farm up He's a Uganda landowner who took his technical degree and started chicken farming, He keeps trying to mitigate the costs of chicken feed with growing his own. He too wants to be a good land steward and teach while he's making mistakes as well as progress.
Thanks… we do use the roller crimper as much as possible, but often it doesn’t completely terminate the cover. We ran the crimper on the sun hemp and it took care of 80-90% of it, but 10-20% Sun hemp is way too much in the wheat crop after. Mowing again doesn’t kill the cover.
By adding active (microbially accessible) carbon sources WITH any nitrogen input you give microbes a ready source of C energy to quickly mineralize the N without depleting organic C already in the soil. Graeme Saits recommends humic/fulvic acids at 5% of actual N input by weight.
Decomposing plant residues is performed by particular bacteria and fungi. Adding a source of N can help some of them to grow & work more quickly, but some not. IMO from my studies, it is almost always better to add active C, because most crop residues (of the same year/growing season) have enough N but not enough ready-to-eat (active) C for the microbes to grow rapidly & do the hard work of breaking down lignin and cellulose.
@@williamgibson2760 sorry but i didnt understood what u said so can u tell me in simple words? Is there any other mathod to decampose high carbon residue without urea ??
Organic Waste Decomposer made from preparation of different bacterial species and a few strains of Aspergillus fungus species, mixed with 1kg of Jaggery in 100 litres of water. Spray 1000 litres of such preparation on rotavated green manure in one Acre area. Spray same quantity at an interval of 25 days on the decomposing matter, so that we can expect full decomposition , which will not affect transplantation of seedlings.This quick Decomposition helps to go for early transplantation of next season crop.

By adding active (microbially accessible) carbon sources WITH any nitrogen input you give microbes a ready source of C energy to quickly mineralize the N without depleting organic C already in the soil. Graeme Saits recommends humic/fulvic acids at 5% of actual N input by weight.
Decomposing plant residues is performed by particular bacteria and fungi. Adding a source of N can help some of them to grow & work more quickly, but some not. IMO from my studies, it is almost always better to add active C, because most crop residues (of the same year/growing season) have enough N but not enough ready-to-eat (active) C for the microbes to grow rapidly & do the hard work of breaking down lignin and cellulose.
@@williamgibson2760 sorry but i didnt understood what u said so can u tell me in simple words? Is there any other mathod to decampose high carbon residue without urea ??
@@Ultimatefitness360sure. Fish and soy hydrolysate.
Organic Waste Decomposer made from preparation of different bacterial species and a few strains of Aspergillus fungus species, mixed with 1kg of Jaggery in 100 litres of water. Spray 1000 litres of such preparation on rotavated green manure in one Acre area. Spray same quantity at an interval of 25 days on the decomposing matter, so that we can expect full decomposition , which will not affect transplantation of seedlings.This quick Decomposition helps to go for early transplantation of next season crop.
