Soil biodiversity represents the variety of life belowground whose interaction with plants and small animals forms a web of biological activity. It improves the entry and storage of water, resistance to soil erosion, and plant nutrition, while also controlling soil pests and disease, and facilitating recycling of organic matter in the soil. Soil biodiversity is therefore the driver of healthy soil for sustainable crop production. 
Sustainable Soil Management for Food Security in South Asia
The soils of South Asia provide food to almost 1.8 billion people but are prone to many sustainability issues. The ever-increasing population has put enormous pressure on the available natural
Collembola communities and soil conditions in forest plantations established in an intensively managed agricultural area
The soils in the two afforested sites were similar in their properties and Collembola communities to those of the control cultivated forests, but differed from each other in pH, calcium, phosphorus, and ammonium content.
Identifying potential threats to soil biodiversity
It is found that many soil biodiversity studies do not focus on biodiversity sensu stricto, rather these studies examined either changes in abundance and/or diversity of individual groups of soil biota, instead of soil biodiversity as a whole, encompassing all levels of the soil food web.
Co-occurrence and diversity of soil trichoderma and fusarium species from different land use intensities in Machakos county, Kenya
There was a clear negative correlation between Trichoderma and Fusarium occurrence and diversity and it was revealed that disturbance had a positive effect on FUSarium but a negative one on Trichodma.
Influence of Sustainable Agricultural Practices on Healthy Food Cultivation
Sustainable agricultural systems aim to use technologies that do not cause any adverse effects to environmental goods and services. To solve the problem of food insecurity due to the increasing
Short-term Impacts of Tillage and Fertilizer Treatments on Soil and Root Borne Nematodes and Maize Yield in a Fine Textured Cambisol
Abstract Conservation agriculture (CA) based on the principles of minimum soil disturbance, crop residue retention, and crop rotation has been the focus of intensive research in recent years. A study

Biochar has been indicated as an amendment to degrade soils, improve carbon sequestration and increase agronomic productivity and future carbon trading markets. Intensive research has confirmed that
Conventional and Conservation Seedbed Preparation Systems for Wheat Planting in Silty-Clay Soil
Conventional seedbed preparation is based on deep ploughing followed by lighter and finer secondary tillage of the superficial layer, normally performed by machines powered by the tractor’s Power
Productivity of tef [Eragrostis tef] under conservation tillage practices in central Ethiopia
Reduced tillage with residue retained can be recommended as an alterantive tillage practice for resource poor farmers in central Ethiopia without significantly affecting yield.

Generally macrofauna density was higher in arable systems than forests, although the differences were not always significant, and the three groups (Chilopoda-Geopholomorpha, Chilo- Scolopendromorpha and Isopoda) were significantly highest in the forests than in all the other land use systems.
An overview of the diversity of microorganisms involved in decomposition in soils
There is a need, in Kenya and in other tropical countries, to focus more research on the gradual changes in diversity at finer levels of taxonomic resolution, and relating these changes to effects on ecosystem function as agriculture intensifies.
Improved seedling emergence and growth of maize and beans by Trichoderma harziunum
Increased growth of shoot and root caused by Trichoderma implied that there was beneficial effect of inoculation on plant growth and development since root collar and stem diameters were a measure of survivability of seedlings.
In Kenya, the below-ground biodiversity (BGBD) project selected two benchmark sites for the inventory of soil biota; these included the Irangi and Ngangao forest sites in the Mount Kenya region of
Detection and Isolation of Soil Fungi
In isolation of soil fungi, extraction and preparation of samples isolation techniques culturing techniques and basal media techniques and selective media.
Comparative description of land use and characteristics of belowground biodiversity benchmark sites in Kenya = Descripción comparativa de usos del suelo y características de la diversidad del subsuelo en sitios empleados como referencia en Kenia
It was concluded that the decline in soil quality and productivity was linked to increased land use intensification due to lack of knowledge of the appropriate management practices for sustainable ecosystem functions and services.
