1. The Effect of Sulfur Fertilization of Yield and Quality of Corn and AlfalfaThe importance of sulfur (S) fertilizers for crop production in Minnesota has been recognized for several years. Inpast research, the use of S had increased crop production only on the sandy soils. Since the soil organic matter is a major reservoir of S for plant use, there is always some question about the need for S in a fertilizer program where soils are not sandy but, yet, have a low organic matter content. It is well known that S is an important component of some amino acids in wlants and this... |
2. Chemical and Biological Changes Resulting from Soil SubmergenceFlooding of a soil for rice production results in significant short and long term physical, chemical and biological changes in soil properties. These changes may have significant impact of the availability of nutrients for plant growth both for aquatic plants growing in the flooded soil and upland plants on the soil when not under flooded conditions. Chief among these nutritional effects are accelerated nitrogen (N) losses, conversion of phosphorus (P) to more available forms during flooding then... |
