A project of the CGIAR systemwide program on Soil, Water and Nutrient Management (SWNM), concerned with improving integrated nutrient management practices on small-scale farms in Africa, has been carried out in Kenya, Tanzania and Uganda for last two years (September 1999 to September 2001). The project aims to enable small-scale farmers to profitably reverse nutrient depletion of their soils b...

The study comparatively assessed the impacts of farm activities on the abundance and diversity of soil arthropods and soil physico-chemical parameters of the Practical Year Training Programme (PYTP) farmlands, University of Ibadan, South Western Nigeria. Soil arthropods were collected from September, 2010 to February, 2011 in five sampling sites of PYTP farmlands using Berlese Tullgren Extracti...

We identi®ed and measured changes in soil characteristics, nutrient availability and microbial activity to a gradient of grazing intensity in the Chaco region of northwestern Argentina (248 430 S and 638 170 W). Three sites were selected for comparison: 1. highly restored (no grazing for 20 years); 2. moderately restored (eight years of restoration); and 3. highly degraded (a typical Chaco camp...

Soil microorganisms have a primary catabolic role in the environment through degradation of plant and animal residues. The activities of microorganisms in soil are thus, essential to the global cycling of nutrients. As these pesticides are designed to be biologically active, their continuous use might affect soil microflora either by changing their properties or their numbers, which may lead to...

In many parts of the world food security is at risk. One of the biophysical root causes of falling per-capita food production is the declining quality and quantity of soils. To reverse this trend and increase soil fertility soil and plant nutrients have to be replenished. This review provides a literature survey of experiences of using multi-nutrient rock fertilizers for soil fertility enhancem...

Although fertility capability classification (FCC) has high performance in land evaluation and soil maps interpretation, so far it has been less attended in land evaluation studies. Therefore, qualitative (FCC method) and quantitative (Riquer index) land fertility capability evaluation for Wheat and Rice cultivation and comparison of Soil Taxonomy and WRB classification with FCC were chosen as ...

During forest succession, litterfall nutrient fluxes increase significantly. The higher inputs of organic matter and nutrients through litterfall affects positively soil fertility and the species composition, which are essential components in forest restoration and management programs. In the present study, the input of nutrients to the forest soil via litterfall components was estimated for tw...

The effects of wood ash fertilization on soil chemical properties were studied in three young Scots pine (Pinus sylvestris L.) plantations and a Norway spruce (Picea abies (L.) Karst.) plantation with different site fertility in southern Finland. The dose of 3 t ha–1 of loose wood ash was applied to 4 replicate plots (25 × 25 m) at each experiment. Humus layer and mineral soil samples were take...

Background: The EU-project Flourish intends to establish an autonomously operating precision farming system based on the interaction between unmanned ground vehicles (UGVs) and unmanned aerial vehicles (UAVs). For effective mission planning and site-specific ground intervention by the UGV, the growth, mineral nutrition, weed, and health status of the crop field must be evaluated efficiently. In...
