Effects of elevated atmospheric CO2 in agro-ecosystems on soil carbon storage
Increasing global atmospheric CO2 concentration has led to concerns regarding its potential effects on the terrestrial environment. Attempts to balance the atmospheric carbon (C) budget have met with a large shortfall in C accounting (μ1.4 3 1015 g C y–1) and this has led to the hypothesis that C is being stored in the soil of terrestrial ecosystems. This study examined the effects of CO2 enric...
متن کاملEffect of application of different pesticides to soybean on the soil microflora.
Pesticide residues contributing to the contamination of soil may influence microbial population of the soil and in turn fertility of soil. The present paper reports the effect of pesticides applied to soybean i.e. phorate, carbofuran, carbosulfan, thiomethoxam, imidacloprid, chlorpyriphos and monocrotophos on soil microflora. The viable count of rhizobia and phosphate solubilizing bacteria from...
متن کاملEffects of pesticides on yeasts isolated from agricultural soil.
The effect of six various pesticides on the growth of yeasts isolated from agricultural soil was investigated. Two herbicides (with the effective substances lactofen and metazachlor), two fungicides (with the effective substances fluquinconazole and prochloraz), and two insecticides (with the effective substances cypermethrin + chlorpyrifos and triazamate) were tested. It is evident that there ...
متن کاملEvaluation of soil fertility status in various agro ecosystems of Thrissur District, Kerala, India
This study was conducted to evaluate soil fertility status in the eight major agro ecosystems viz., coconut, banana, rubber, paddy, arecanut, nutmeg, pepper and vegetables in Thrissur District, Kerala. For this, a total of 30 panchayats out of 92 were selected representing 6 agro ecological zones in the district. Surface soil samples (0-15 cm) @ one sample/ ha. were collected from dominant agro...
