Recovery of residual fertilizer-nitrogen by wheat in a winter wheat–summer maize rotation in the north china plain: A soil column study
Cropping systems is potentially useful practice for mitigating nitrate leaching and increasing nitrogen use efficiency (NUE) because deeper rooted crops could capture the leached N from previous shallower rooted crops. The recovery of fertilizer nitrogen (FN) applied to maize (Zea mays L.) by the succeeding wheat (Triticum aestivum L.) in a winter wheat–summer maize rotation in North China Plain ...

Elemental composition of Jamaican foods 1: A survey of five food crop categories
The concentrations of 27 elements in Jamaican food categories consisting of fruit, legumes, leafy and root vegetables and other root crops are reported. The main analytical techniques used were neutron activation analysis and flame and graphite furnace atomic absorption spectrophotometry. The results are compared, where possible, with values from Denmark, the United Kingdom, the United States and ...

Nitrate leaching from a potato field using adaptive network-based fuzzy inference system
The conventional methods of application of nitrogen fertilizers might be responsible for the increased nitrate concentration in groundwater of areas dominated by irrigated agriculture. Appropriate water and nutrient management strategies are required to minimize groundwater pollution and to maximize nutrient use efficiency and production. Design and operation of a drip fertigation system ...

PRZM-3, A Model for Predicting Pesticide and Nitrogen Fate in the Crop Root and Unsaturated Soil Zones: Users Manual for Release 3.12.2
This publication contains documentation for the PRZM-3 model. PRZM-3 is the most recent version of a modeling system that links two subordinate models – PRZM and VADOFT – in order to predict pesticide transport and transformation down through the crop root and unsaturated soil zones. Enhancements to Release 3.0 reported herein include algorithms that also enable modeling of the nitrogen cycle ...

Soil water movement under a drip irrigation double-point source
Particularly in dry regions, the scarcity of high-quality fresh water has heightened the importance of urban runoff water re-use, leading as well to the improvement of water use efficiency through the surface drip irrigation method. Given the limited research on wetting front migration under a surface drip irrigation emitter, soil water movement under a double-point-source irrigation emitter ...

What Are The Advantages Of Cassava Starch?
Cassava of Goodway has many advantages for cassava starch production. High level of purity. Excellent thickening characteristics. A neutral (bland) taste. Desirable textural characteristics. A relatively cheap source of raw material containing a high concentration of starch (dry-matter basis) that can equal or surpass the properties offered by other starches (maize,wheat, sweetpotato, and ...

Accumulation and translocation of 198Hg in four crop species
The uptake and transport of mercury (Hg) through vegetation play an important role in the biogeochemical cycling of Hg. However, quantitative information regarding Hg translocation in plants is poorly understood. In this study, Hg uptake, accumulation and translocation in four corps rice (Oryza.sativa L.), wheat (Triticum L.), corn (Zea mays L.) and oilseed rape (Brassica campestris L.) grown ...

Nitrogen influences biomass and nutrient partitioning by perennial, warm-season grasses
Recent attention has focused on the use of perennial, warm-season grasses as renewable energy crops. The objective of this study was to assess the effects of N fertilization on partitioning of biomass and nutrients between above- and belowground plant components by four warm-season grass species in Iowa. In 2006–2007, established stands of big bluestem (Andropogon geradii Vitman), switchgrass ...

Toxic effects of wastewater from various phases of monosodium glutamate production on seed germination and root elongation of crops
To make a comprehensive assessment on monosodium glutamate (MSG) wastewater pollution, a pollution exposure experiment was carried out on the seed germination and root elongation of wheat, Chinese cabbage and tomato by using the wastewater discharged from different processing phases of MSG production. The results showed that there were significantly positive linear relationships between the ...

Soil moisture dynamics modeling considering multi-layer root zone
The moisture uptake by plant from soil is a key process for plant growth and movement of water in the soil–plant system. A non-linear root water uptake (RWU) model was developed for a multi-layer crop root zone. The model comprised two parts: (1) model formulation and (2) moisture flow prediction. The developed model was tested for its efficiency in predicting moisture depletion in a ...

Effect of loblolly pine root pruning on alley cropped herbage production and tree growth
Tillage to disrupt (prune) tree roots is an intensive practice which could improve herbage productivity at the crop–tree interface by reducing competition for water. We compared tillage effects on 9- to 11-yr-old loblolly pine (Pinus taeda L.) growth and herbage yields of annual ryegrass (Lolium multiflorum Lam.) and pearl millet [Pennisetum glaucum (L.) R. Br.] on a fragipan soil in Arkansas. ...

Multisensor Capacitance Probes for Simultaneously Monitoring Rice Field Soil-Water-Crop-Ambient Conditions
Abstract: Multisensor capacitance probes (MCPs) have traditionally been used for soil moisture monitoring and irrigation scheduling. This paper presents a new application of these probes, namely the simultaneous monitoring of ponded water level, soil moisture, and temperature profile, conditions which are particularly important for rice crops in temperate growing regions and for rice grown with ...

Local advice on managing blackgrass
Blackgrass is a weed that troubles many, and controlling it is an increasing challenge, particularly with the small armoury of products available, and the growing issue with resistance. Paul Drinkwater, Crop Production Manager for Abbots Ripton Farming Company, explains how, in his 40 years of being in the Cambridgeshire area, the blackgrass problem has evolved. “My role sees me manage ...

Reuse of Dairy Lagoon Wastewater Through SDI in Forage Crops
Abstract California has become the leading dairy products producing state in the USA. This has resulted in farms commonly milking several thousand cows per day. The care and feeding of the animals has produced large waste streams commonly collected and stored in lagoons. Environmentally safe handling and reuse of the lagooned wastewater is the objective of this study. A system of Subsurface Drip ...

Irrigation and Nitrogen Best Management Practices Under Drip Irrigated Vegetable Production
Abstract Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several ...

What Is Cassava Starch?
Starch is one of the most abundant substances in nature, a renewable and almost unlimited resource. Starch is produced from grain or root crops. It is mainly used as food, but is also readily converted chemically, physically, and biologically into many useful products to date, starch is used to produce such diverse products as food, paper, textiles, adhesives, beverages, confectionery, ...

Hydroponic Spacer, the solution to Crazy Roots
Among the many diseases that can affect the root zone of the plant, bacterial diseases stand out for being potentially very harmful.. The main problem of these diseases is that there is no effective control of them through chemical treatments, so once the disease takes place it causes severe damage to the crop, reducing production and quality. The most effective way to avoid the negative impact ...
