Spatial prediction of soil organic matter content using cokriging with remotely sensed data
Accurately measuring soil organic matter content (SOM) in paddy fields is important because SOM is one of the key soil properties controlling nutrient budgets in agricultural production systems. Estimation of this soil property at an acceptable level of accuracy is important; especially in the case when SOM exhibits strong spatial dependence and its measurement is a time- and labor-consuming ...

Soil organic matter content effects on dermal pesticide bioconcentration in American toads (Bufo americanus)
Pesticides have been implicated as a major factor in global amphibian declines and may pose great risk to terrestrial phase amphibians moving to and from breeding ponds on agricultural landscapes. Dermal uptake from soil is known to occur in amphibians, but predicting pesticide availability and bioconcentration across soil types is not well understood. This study was designed to compare uptake ...

Summer cover crop and management system affect lettuce and cantaloupe production system
Cover crops are widely used in both conventional and organic systems to protect and improve the soil. This study evaluated the effect of summer cover crop and management system on the production of fall romaine lettuce (Lactuca sativa L.) and spring cantaloupe (Cucumis melo L.) from 1999 to 2003. Cover crop treatments included cowpea [Vigna unguiculata (L.) Walp.] incorporated (CPI), cowpea used ...

Dryland crop yields and soil organic matter as influenced by long-term tillage and cropping sequence
Novel management practices are needed to improve the declining dryland crop yields and soil organic matter contents using conventional farming practices in the northern Great Plains. We evaluated the 21-yr effect of tillage and cropping sequence on dryland grain and biomass (stems + leaves) yields of spring wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), and pea (Pisum sativum L.) and ...

Long-term study of properties of a xerofluvent of the guadalquivir river valley under organic fertilization
The long-term effect of inorganic and organic fertilization in a vegetable crop rotation on soil chemical and biochemical properties was investigated in a trial in southern Spain. Two crops were grown in succession, potato (Solanum tuberosum L.) and a mixed-cropped strawberry–onion (Fragaria vesca L.–Allium cepa L.). Total organic carbon (TOC), Kjeldahl-N, bicarbonate-extractable P (Olsen-P), ...

Fertilization management of paddy fields in Piedmont (NW Italy) and its effects on the soil and water quality
The fertilization management of the rice crop in Piedmont was analyzed at a regional scale, and the agronomic and environmental sustainability of the actual fertilization strategy of rice was evaluated through the analysis of its effect on the soils and waters quality. On average, a total amount of 127 kg ha − 1 of N, 67 kg ha − 1 of P 2 O 5 and 161 kg ha − 1 of K 2 O were ...

Biological responses of Vicia faba seedlings to the imidazolium‐based ionic liquid 1‐hexyl‐3‐methylimidazolium chloride in soil
Although there are a few studies on the toxicity of ionic liquid (ILs), relatively little is known about the toxic effects of these liquids in the soil on plants. In the present study, the toxic effects of 1‐hexyl‐3‐methylimidazolium chloride ([Hmim]Cl) in the soil on Vicia faba (V. faba) seedlings and the influences of [Hmim]Cl on the physicochemical properties of the soil were studied. The ...

Sorption and degradation of wastewater-associated pharmaceuticals and personal care products in agricultural soils and sediment
Pharmaceuticals and personal care products (PPCPs) have drawn popular concerns recently as an emerging class of aquatic contaminants. In this study, adsorption and degradation of four selected PPCPs, metronidazole, tinidazole, caffeine and chloramphenicol, have been investigated in the laboratory using two agricultural soils in China and sediment from Changjiang River. Adsorption tests using a ...

Can We Prevent A Food Breakdown?
By Lester R. Brown As food supplies have tightened, a new geopolitics of food has emerged—a world in which the global competition for land and water is intensifying and each country is fending for itself. We cannot claim that we are unaware of the trends that are undermining our food supply and thus our civilization. We know what we need to do. There was a time when if we got into trouble ...

Why organic fertilizer equipment is suitable for small investment
In agricultural production, in order to achieve the increase of crop production, people do not hesitate to pour a large number of chemical fertilizer into the farmland. More and more nitrogen, urea and nitrogen, phosphorus, potassium compound fertilizer are used, and the concentration is higher and higher. Although this has kept the effect of increasing production to a certain extent, the ...

Advantages and precautions of NPK organic fertilizer granulator
The humus in organic fertilizer increases the content of soil organic matter, which is beneficial to the formation of good soil structure, especially the increase of water stable aggregate structure, so as to improve the tightness, aeration, water retention and heat status of soil, and has a good effect on the water, fertilizer, air and heat conditions that determine the soil fertility. It is ...

Multivariate analysis and visualization of soil quality data for no-till systems
To evidence the multidimensionality of the soil quality concept, we propose the use of data visualization as a tool for exploratory data analyses, model building, and diagnostics. Our objective was to establish the best edaphic indicators for assessing soil quality in four no-till systems with regard to functioning as a medium for crop production and nutrient cycling across two Illinois ...

Six effects of organic matter on maintaining soil fertility
The content of soil organic matter is closely related to the level of soil fertility. Although organic matter only accounts for a small part of the total amount of soil, it plays a significant role in maintaining soil fertility. The manufacturer of organic fertilizer production equipment introduces six important functions of organic matter to maintain soil fertility. 1. Provide nutrition for ...

Benefits of applying organic fertilizer to oil palm
Oil palm is a perennial evergreen gymnospermous woody plant. It not only consumes a large amount of nutrients, but also has characteristics of nutrient demand. In addition to N, P, K and trace elements, the demand for lignocellulose is higher. It is not enough to plant oil palm only by using chemical compound fertilizer. The predatory use of soil will eventually lead to the deterioration of soil ...

How to maintain soil fertility
In order to maintain soil fertility, some low-yield soil (acid soil, alkali soil and salt soil), chemical improvers and irrigation should be used to improve, remove obstacles and improve the fertility level. In addition, reasonable cultivation and rotation should be carried out to regulate the nutrients and water in the soil and prevent some nutrient deficiency and water vapor imbalance. 1. ...
