Agriculture yields

Over decades, pesticide applications have contributed to increasing agricultural yields in the production of many crops in the USSR and, in... 

Pesticides Those chemicals used in agriculture to control the severity and incidence of pests and diseases which reduce agricultural yields in addition, they have a number of non-agricultural uses. pH Means used to express the degree of acidity or alkalinity of a solution with neutrality indicated as 7. 

An important side-effect of global warming could be that cultivation zones will shift pole-wards and that agricultural yields will be affected. Reilly et al. (1996) and others expect that extreme climatic events will occur more frequently and that this will jeopardise plant production.

Both salinity and sodicity impair plant growth and reduce agricultural yields. In severe cases, they can cause complete crop failure (Qadir et al. 2000). Plants on saline areas suffer from lack of water, because salts bind water in the soil and thus make it inaccessible to plants and microorganisms. Beside this osmotic stress situation, an excess of specific ions, such as sodium, is toxic to plants or results in an ion imbalance, which complicates the uptake of specific nutrients (Marschner 1995). Some crops have developed tolerance to salty conditions and can thus be used to a certain extent on soils affected by salinity.

The chronic and acute response of agricultural crops and livestock to some contaminants, such as metals, is known from experimentation and guideline values are available. However, site-specific factors such as irrigation of crops and supplementary feeding of livestock can influence receptor exposure and there is a large impact of soil and local environmental conditions on agricultural yields, so field trials may be justified.

Poly(lactic acid) (PLA) is known to be biocompatible and biodegradable, and it can be readily broken down by a hydrolysis reaction. PLA is derived from renewable agricultural resources, such as com and cassava. Mass production of PLA can lead to high consumption of agricultural yields, which increases the farm economy. Moreover, the production of PLA helps to reduce CO2 emissions when used in place of conventional petroleum-based commodity plastics, as the agrieultural activities involve significant carbon fixation.
