Changes in Soil Properties Under No-Tillage,ironment favorable for the numerous necessary biological reactions. The microbial activity of the soil is largely determined by the chemical and physical properties of the soil. For example, the placement and amount of organic material directly influences biological activity, as it also does the chemical and physical properties.

Soil Adaptability for No-Tillage,be carefully evaluated before selecting a tillage system. Soil conditions that favor no-tillage farming or modifications of these systems will be discussed in this chapter as well as conditions that are less favorable for the adoption of no-tillage farming techniques.

Fertilization and Liming,al. The presence of a surface mulch changes the soil water regime, particularly at the soil surface. Principles of fertilization and liming for no-tillage are based on these two conditions as well as on the nutrient requirements of plants and the specific soil and climatic conditions encountered.

Effects of Climate on Performance of No-Tillage,uly (see Table 4-1). From Table 4-1, it can be seen that the average water use, soil water evaporation plus transpiration, by corn for the 1970, 1971, and 1972 and 1973 growing seasons (May through September) on the conventional tillage treatment were 35.5, 51.4, 35.5 and 50.6 cm, respectively.

Energy Requirement in No-Tillage,on and for grain drying, especially in large commercial operations. Much of the indirect use of natural gas in agriculture is in the form of nitrogen fertilizer, since almost all nitrogen fertilizer used in the U.S. is manufactured from natural gas. An estimated 89 percent of the energy used in prod
