50°F: Significant nitrogen release occurs in the soil.
86°–
95°F:The maximum nitrogen release point is
reached in the soil.
90°F: The pollination process begins to decrease.
95°–
104°F:A significant decrease in nitrogen release
occurs in the soil.
131°F: Nitrogen release stops in the soil.One of the exciting things about the GROW
BIOINTENSIVE method is its emphasis on the soil. Once
you know how to prepare soil well for vegetables, a
whole world of crops becomes available to you. The bed
preparation, fertilization, and watering approaches
remain essentially the same—only the plant spacings are
different!
These charts will help you expand from growing only
vegetable crops to including plants from the following
broad groups:
- Grains, protein sources, and vegetable oil crops.
- Compost, organic matter, and fodder crops. Some
compost crops, such as pearl millet, sorghum, and
corn, can produce very high yields of biomass and
should be fully recycled through composting whenever
possible to minimize the potential for soil depletion. - Energy, fiber, paper, and miscellaneous crops.
- Tree and cane food crops.
