Weeds are an index of what is wrong — and sometimes what is right — with the soil, or at least with the fertility program. In every field on every farm, there are different soil types, and each has a potential for producing certain weeds, depending on how a farmer works the soil. Fall tillage, […]

The soybean is a truly amazing and versatile crop plant. It is one of the oldest food plants, domesticated by 1100 BC in northeastern China. Its ancestor is a wild vine-like plant that produces tiny, hard seeds that are useless for food unless properly prepared.
As those billions of microbes in a handful of soil go through their life cycles living and dying, they are providing a constant source of nutrients. Arbuscular mycorrhizal fungi are capable of passing both organic and inorganic forms of phosphate to plants. One of the huge differences between our cropland soils and natural ecosystems is […]
Farming has to be a paying proposition — that is, the farmer has to be paid a fair profit as are other segments of the economy. Until such changes come about, one way to “beat the system” is to grow higher quality crops with less dollar input. Crops that command premium prices on the market, […]
In his book Science in Agriculture, author Arden B. Anderson sought to apply true, natural science to agriculture. Readers should gain a working knowledge of chemistry, physics, and plant biology as applied to agriculture; discover what weeds are communicating about your soil’s fertility needs; and learn how to design and implement a program to produce […]
Carbon is an often overlooked, but very important component of the soil. We know how to manage nitrogen, phosphorus and potassium for maximum production, and that micronutrients play a critical role in crop yield and disease resistance. Deficiencies can usually be corrected relatively quickly through the addition of soil or foliar fertilizer applications. While soil […]
