His primary areas of study are Agronomy, Manure, Soil water, Fertilizer and Loam. His work deals with themes such as Conservation agriculture and Soil fertility, which intersect with Agronomy. Soil water and Sludge are commonly linked in his work.
His Sludge research focuses on Effluent and how it relates to Wastewater and Irrigation. His Fertilizer research includes elements of DNS root zone, Soil carbon, Dry matter and Leachate. His study in Loam is interdisciplinary in nature, drawing from both Environmental chemistry, Lessivage, Pasture and Lixisol.
His scientific interests lie mostly in Agronomy, Soil water, Agroforestry, Manure and Soil fertility. His studies deal with areas such as Soil management and Soil carbon as well as Agronomy. The various areas that he examines in his Soil water study include Sludge, Wastewater and Effluent.
His study on Agroforestry also encompasses disciplines like
Justice Nyamangara spends much of his time researching Agronomy, Agroforestry, Conservation agriculture, Soil water and Soil carbon. Justice Nyamangara interconnects Loam and Soil test in the investigation of issues within Agronomy. His Agroforestry study integrates concerns from other disciplines, such as Nutrient management, Soil management, Soil fertility and Crop management.
His work investigates the relationship between Conservation agriculture and topics such as Plough that intersect with problems in Soil quality. Much of his study explores Soil water relationship to Crop yield. His studies in Manure integrate themes in fields like Fertilizer and Organic fertilizer.
Justice Nyamangara mainly focuses on Conservation agriculture, Agronomy, Plough, Soil water and Soil carbon. In his study, which falls under the umbrella issue of Conservation agriculture, Weed, Crop rotation, Weed control and Soil type is strongly linked to Tillage. His Agronomy study integrates concerns from other disciplines, such as Forest floor, Agroforestry and Pinus patula.
The concepts of his Plough study are interwoven with issues in Soil science, Soil quality, Soil test, No-till farming and Loam. The various areas that he examines in his Soil water study include Mulch, Manure and Sowing. His Soil carbon study incorporates themes from Humus, Total organic carbon and Thinning.
