Nutrient Cycle Timing, Spader vs Tiller, Tractor Size

Drake opens with an I Ching reading on modesty, then covers the mechanics of the farm. He explains that tractors rarely compact soil by their weight; it's tillage followed by rain that forms hardpan under the plow layer. He runs a New Holland 1510 and recommends the smallest tractor that does the job, with LAB (protectors) diluted 1:20 to 1:50 and IMOs to break up compaction. He also compares his Italian spader, run at low RPM, against a standard tiller.

On foliar sprays, Drake says all nine core KNF solutions (microbes, protectors, food, cleanser, medicine, structure, fuel, reproduction, minerals) can be mixed safely, but the maintenance, bloom, and fruit formulas give better results. The maintenance formula runs roughly 8ml food, 8ml cleanser, 4ml medicine, 4ml structure per gallon, and up to three different KNF Foods can be blended into one batch without changing those ratios.

He details the nutrient cycle: childhood growth uses food made from growth tips (nitrogen), puberty uses food from unripe fruit and flowers (phosphorus), and the reproductive stage uses food from ripe fruit (potassium), matching each plant's natural chubby-skinny oscillation. He cites Dr. Bugbee at Utah State on foliar feeding over root overfeeding, and names bamboo, comfrey, and horsetail as good exudate plants.

Drake asks viewers with Sri Lanka contacts to translate and share two recipes farmers there need after the country's organic mandate collapsed: a boiled-starch microbe brew and a rotted-leaf juice diluted 1:100. He closes with advice for heavy clay soil (IMOs, organic matter, biochar, no gypsum) and microgreens (use the Leaf Formula, skip reproduction).

Questions answered

  • 6:57 What classes is Drake teaching at Hawaiian Sanctuary? — Simplified natural farming on August 11 and livestock (no-smell pigs and chickens) on August 18.
  • 20:45 No rain for a month and never watered — how are the plants still thriving? — Microbes and good biochar pull condensation out of the air underground, so you don't need rain to keep soil moist.
  • 23:25 Any resources for doing KNF in the desert? — Check Microbial Secret Society (microbialsecret.org) under micro-celebrities for Sam Bevans, who farms KNF in the Israeli desert.
  • 26:11 What's the biggest tractor size before it damages soil structure? — Tillage plus rain compacts soil more than tractor weight; get the smallest tractor for the job, and LAB/IMOs break up any compaction.
  • 30:11 Any solutions you shouldn't mix in the same foliar sprayer? — No — all nine core solutions can go in one sprayer; follow the maintenance/bloom/fruit formulas, and rinse with diluted LAB to clear contamination.
  • 33:14 Growing lettuce, cabbage, and fruiting tomatoes/eggplant — do I need two maintenance solutions? — No — mix up to three different KNF Foods into one maintenance batch without changing the other ratios.
  • 35:13 What's the difference between a spader and a tiller? — A spader's shovels punch down and pop up to break the top layer instead of inverting it like a tiller; run it at low RPM, almost idling.
  • 37:48 Do flowers follow the same fat/skinny feeding schedule as regular crops? — Yes — plants cycle chubby-skinny through childhood, puberty, and reproduction; shift the KNF Food from growth tips to unripe fruit to ripe fruit as it matures.
  • 52:13 What did Dr. Bugbee at Utah State say about root feeding? — A hungry root has more vigor than an overfed one, so feed foliarly and let roots reach into the soil for microbes instead of amending the hole.
  • 53:50 What plants make good general-purpose foliar exudates? — Bamboo and comfrey are the most general-purpose; horsetail is good too because of its silica.
  • 54:35 Sri Lanka's organic mandate destroyed farms — what do they actually need? — They need the boiled-starch microbe recipe and a rotted-leaf juice diluted 1:100, not expensive extras — please translate and share these two recipes.
  • 57:56 Any advice for heavy clay soil with little organic matter? — Use IMOs, add organic matter and a little biochar, and skip the gypsum.
  • 1:01:10 What foliar feed works best for microgreens? — Use the Leaf Formula — food from sprouts plus cleanser, medicine, structure, fuel, and protectors — and skip reproduction since they won't fruit.
