A Survey of Soil Fertility Status of Four Agroecological Zones of Mozambique
Mozambique includes 10 agroecological zones with distinct climate and cropping systems (INIA, 1980). Agricultural production is more intensively practiced in the central and northern parts of the country where agroecological conditions are favorable. As a result of 16 years of civil war and low funding for agricultural research few assessments of soil nutrient status have been possible. To asse...
متن کاملRole of soil fertility management on productivity of sesame and cowpea under different cropping systems
ABSTRACT- Declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. The field experiment with different rates of fertilizer systems (60 kg ha-1 N + 100 kg ha-1 P, 300 kg ha-1 Bio-organic (organic fertilizer), 3 kg ha-1 Bioumik (biofertilizer), 30 kg ha-1 N + 50 kg ha-1 P + 150 kg ha-1 Bio-organic fertilizer and 30...
متن کاملBiological Nitrogen Fixation for Increased Crop Productivity, Enhanced Human Health and Sustained Soil Fertility
FAOSTAT 2002 Nitrogen is, with water, the greatest global constraints to agricultural productivity. Sustainable cropping systems throughout history have relied on combining cereals with nitrogen-fixing legumes. However, over last fifty years, cereals have dominated global agriculture, while legume cultivation areas and productivity have stagnated or even declined. Global agriculture is now at a...
متن کاملCOMMENTARY: The productivity of variability: an agroecological hypothesis
Most agronomic research seeks to limit the variability of productivity, offering universal ‘recipe knowledge’ that attempts to overwhelm contextual differences. Based on participatory research with a group of eight graziers in Wisconsin, we present the counter hypothesis that the productivity of variability is a key principle of agroecology. Contextual variability across space and time presents...
متن کاملNitrogen and Soil Fertility
amounts involved are much smaller. The amount of boron in the 7-ton potato crop (if determined) would have been about 0.2 pound. In the case of boron (and to a lesser degree the other micronutrients) if the soil contains excessive amounts, toxic quantities are absorbed by plants and growth is restricted. The need for a reasonable balance in amounts of available nutrients in the soil has been po...
