The Use Of Biological Soil Health Indicators To Quantify The Benefits Of Cover Crops, Alexander Wu
The Use Of Biological Soil Health Indicators To Quantify The Benefits Of Cover Crops, Alexander Wu
Masters Theses
Soils provide many essential functions that support the world. With a decline in soil health, these functions also decrease in efficiency, and can threaten the health of billions of people around the world. Typically, soil health tests do not use biological indicators, however microbes drive and perform vital functions to increase soil health. One way to increase soil health is through the use of cover crops to reduce soil erosion during fallow periods, increasing soil organic matter, as well as collecting nutrients from soil into their biomass. These cover crops are then terminated through various methods such as herbicides, disk …
Investigating The Effect(S) Of Contrasting Nitrogen (N), Phosphorus (P), And Potassium (K) Fertilizer Rates On Cassava Tuber Yield And Quality And Maize Grain Yield In Southern Africa, Ivan Bernardo Cuvaca
Investigating The Effect(S) Of Contrasting Nitrogen (N), Phosphorus (P), And Potassium (K) Fertilizer Rates On Cassava Tuber Yield And Quality And Maize Grain Yield In Southern Africa, Ivan Bernardo Cuvaca
Masters Theses
Fertilizer is a major limiting factor to agriculture in southern Africa (SA). Coupled with this is lack of appropriate fertilizer recommendation rates for high productivity in existing agricultural systems. Field experiments were conducted to determine nitrogen (N), phosphorus (P), and potassium (K) fertilizer rates for high cassava tuber yield and quality for the coastal semiarid Dondo District of Mozambique, and high maize grain yields for both vertisol and inceptisol of Maphutseng in Lesotho. In general, the results showed that cassava tuber yield, cassava tuber quality as measured by tuber starch content, and maize grain yield were significantly increased by fertilizer …
