It has been proposed that the large soil carbon (C) stocks of humid tropical forests result predominantly from C stabilization by reactive minerals, whereas oxygen (O2) limitation of decomposition has received much less attention. We examined the importance of these factors in explaining patterns of C stocks and turnover in the Luquillo Experimental Forest, Puerto Rico, using radiocarbon (C) me...

Understanding the spatial variability of herbicide sorption to soil is important in determining the bioavailability as well as leaching potential of the chemical across a field. Multiple methods have been used to estimate herbicide sorption variability at the macroscale, but it has been difficult to measure soil heterogeneity or herbicide sorption at the individual field level. One method to de...

demand for water resources in different parts of the world, necessitate the use of wastewater. in using wastewater the soil health must be considered. this study was carried out at green space zob ahan in the years 1382 to 1385. in this study, the effects of urban and industrial wastewater irrigation on some chemical properties of soil for three years by using five different irrigation treatmen...

[1] Incoming radiation forcing at the land surface is partitioned among the components of the surface energy balance in varying proportions depending on the time scale of the forcing. Based on a land-atmosphere analytic continuum model, a numerical land surface model, and field observations we show that high-frequency fluctuations in incoming radiation (with period less than 6 h, for example, d...

using low quality water on agricultural lands in south of tehran has increased the risk of soil salinity and created problems for some agricultural crops. this study was carried out to determine of soil salinity distribution and to produce salinity map. the mapping of salinity can also identify the saline and non-saline regions that are very effective for land management and choosing kind of cr...
