Pesticides (mainly herbicides, insecticides, and fungicides) are used to chemically combat certain plants, animals, or microorganisms perceived as harmful to agriculture. Due to the fundamental similarities in all living beings, it is challenging to target unwanted species without affecting others, including humans.

In this study, 341 Bacillus sp. strains were isolated from agricultural soils of Turkey. The potent extracellular lipase producer was selected. It was identified by 16S rRNA, named as Bacillus cereus ATA179. Optimal nutritional and physical parameters for lipase production were determined. Sucrose as the carbon source, (NH4 )2 HPO4 as the nitrogen source, CaCl2 as the metal ion were obtained. The best results of physical parameters were stated at 45°C, pH 7.0, shaking rate 50 rpm, inoculation amount 7% and inoculum age 24 h.

Water stress periods are common in rainfed agriculture therefore the activities aimed at conserving the rainwater should be adopted for improving the productivity of dryland crops. The major crops in Vidarbha region of Maharashtra are cotton, soybean and sorghum. It was observed that the drought situation may arise during crop growth period which may result in partial failure of crops. It was therefore felt worthwhile to adopt the proper methods of in-situ moisture conservation so as to partially meet out the adverse effect of water stress in standing crop.

Copper and zinc are also toxic to humans when high levels are ingested and an excess of copper and zinc interferes with plant growth. It is important to monitor copper and zinc content in soil to avoid marketing food products which contain dangerous amounts of these heavy metals. This article presents the results of a study done to determine the copper and zinc content of soil and four agricultural products grown in Tan Lap Co-operative, Dan Phuong District, Hanoi.

Soil organic carbon (SOC) pool is the largest among the terrestrial pools. The restoration of SOC pool in arable lands represents a potential sink for atmospheric CO2. The management and enhancement of SOC is important for sustainable agriculture. The cropping system and soil type influence crop biomass under different fertilization. Agriculture acts as both the sink and sources of the greenhouse gases.

An understanding of soil microorganisms as part of soil system and interactions between the diversity of producers and of decomposers, have major consequences on the functioning of agricultural ecosystems. Soil microorganisms control the transformation and mineralization of natural compounds and xenobiotics. The soil micro biota, existing in high density and diversity, rapidly modify the energetic performance and activity rates to changing environmental conditions.
