Mapping Soil Fertility at Different Scales to Support Sustainable Brazilian Agriculture
Most agricultural crops cultivated in Brazil are highly nutrient demanding. Brazilian soils are generally acidic with low base saturation and available nutrients. Demand for fertilizer application has increased because the national agricultural sector expansion. To improve productivity without environmental impact, there is the need for the utilization of novel procedures and techniques to opti...
متن کاملSustainable Agriculture: More than One Way Ahead
Recent discussions of the way ahead for agriculture have tended to centre around the frequently incompatible claims of the proponents of technological agriculture, now further developed through inputs from biotechnology , and ecological agriculture, of which organic farming is the best known example.There is a need for the claims made for these two versions to be put into a broader scientific a...
متن کاملSustainable Agriculture, Soil Health, and Soil Organic Matter
The latter two principles protect the soil resource on which all food and fibre production ultimately depends. However, agricultural production systems differ from ‘natural’ or undeveloped systems in that they can be considered to be ‘leaky’ with respect to nutrients. This is inevitable, due to nutrient removal in harvested product, but inappropriate fertiliser management can exacerbate the ‘le...
متن کاملBeneficial Soil Microorganisms: A Key for Sustainable Agriculture
Microorganisms play a major role in the plant-soil relationship, particularly in the rhizosphere, i.e. the interface between root and soil. Rhizosphere is strongly influenced by the root, through its productions (rhizodeposition) and its respiration, as well as uptake of ions and minerals. In this environment, plant beneficial microorganisms are of peculiar importance: they stimulate plant grow...
متن کاملRole of Conservative Agriculture on the Sustainability of Soil structure in Achieving Sustainable Management
Conservative agriculture is considered as an alternative to tackle the need for increased agricultural production based on sustainable agriculture activities with the aim of increasing production and product stability along with preserving the environment. Tillage is one of the most important factors affecting soil structure. Selection of appropriate tillage systems varies according to the cond...
