Miller, J.H. and Newton, M., 1983. Nutrient loss from disturbed forest watersheds in Oregon’s Coast Range. Agro-Ecosystems, 8: 153-167. Dissolved nutrients were monitored bi-weekly in stream water draining 14 upland watetzhcds in Oregon’s Coast Range after sprayin g with 2,4:5-T + 2,4-D, clrarcut harvesting and slash burning. Anion generation and leaching were primarily studied. The nitrate con...

in order to compare the effects of different spraying of nano zinc oxide and zinc oxide, the arable irrigated wheat was conducted in two separate trials in 2011-2014 lands of abadeh city.experiments were conducted in a randomized complete block design, with five treatments and five replications.in the first experiment, treatments included the application of nano zinc oxide to five levels ( 0 , ...

anopheles stephensi is an important malaria vector in southern iran. this species developed resistance to ddt in 1975 and subsequently to dieldrin in 1960. since 1968 this species has been under pressure of malathin house sprayin. 50% w.d.p. , 2g/m2, 1-2 rounds per year. susceptibility tests carried out with malathion impregnated papers during 1979 showed that an.stephensi has acquired resistan...
