Copper phytoavailability and uptake by Elsholtzia splendens from contaminated soil as affected by soil amendments.
Pot and field experiments were conducted to evaluate bioavailability of Cu in contaminated paddy soil (PS) and phytoremediation potential by Elsholtzia splendens as affected by soil amendments. The results from pot experiment showed that organic manure (M) applied to the PS not only remarkably raised the H2O exchangeable Cu, which were mainly due to the increased exchangeable and organic fracti...
متن کاملgrowth, mineral nutrition and selected soil properties of lowland rice, as affected by soil application of organic wastes and phosphorus
lack of adequate organic matter (om) in the agricultural soils of iran is responsible for the poor physical condition of these soils. thus, increasing soil om is very important. on the other hand, the eutrophication of surface water caused by continuous use of phosphorus (p) fertilizer has created an interest in the combined use of organic wastes and p fertilizer. hence, the present study was u...
متن کاملOrganic Phosphorus Source Effects on Calcareous Soil Phosphorus and Organic Carbon
The loading, solubility, mobility, and plant availability of P is a growing environmental concern to regulators and planners of nutrient management plans, confined animal feeding operations, and wastewater land application permit sites. Insufficient information is available on how P reacts from different organic sources when applied to calcareous soils. A field study was conducted to determine ...
متن کاملManganese Toxicity in a Hawaiian Oxisol Affected by Soil pH and Organic Amendments
Although less widespread than Al-toxic acid soils, Mntoxic acid soils do exist in Hawaii (Hue et al., 1998a), Manganese toxicity is a serious constraint to many crops grown Brazil (R.S. Yost, personal communication, 1999), and on acid soils in Hawaii. To develop management strategies to deal with the Mn problem, four experiments were conducted. First, to the Philippines (Hue, 1999). For example...
متن کاملOrganic and inorganic nitrogen amendments to soil as nematode suppressants.
Inorganic fertilizers containing ammoniacal nitrogen or formulations releasing this form of N in the soil are most effective for suppressing nematode populations. Anhydrous ammonia has been shown to reduce soil populations of Tylenchorhynchus claytoni, Helicotylenchus dihystera, and Heterodera glycines. The rates required to obtain significant suppression of nematode populations are generally i...
