Crop Cultivation Applications

Mycotoxins are a diverse group comprised of hundreds of secondary metabolic products of various fungal species. Several show marked toxicity in humans. Contamination of the food supply with mycotoxins is increasingly prevalent, and can occur during growth, harvest, transportation, processing or storage. Techniques to reduce mycotoxin concentration after contamination are expensive, unreliable and sometimes reversible. Therefore, the removal of contaminated products from the food chain is a primary means of eliminating human exposure. The sensitive and accurate detection of very low levels of these compounds is critical to efforts to identify contaminated products. LC-MS/MS is a popular analytical technique for this purpose. This application explores using Ascentis® Express RP-Amide and Ascentis Express F5 HPLC columns to perform this analysis.

Control Composting Odors, Naturally: Municipal sludge is often composted in indoor facilities or composting sheds. These areas create significant odor control challenges. Ecosorb products, either evaporated or atomized in concentrate form with nozzles or humidifying fans, control industrial odors even in very large composting facilities.

The US FDA and international regulatory agencies have set contamination levels for aflatoxins in animal feedstuffs. Since Aspergillus may infect commodities pre-harvest, during storage or during processing, monitoring for aflatoxins in associated agricultural commodities at all stages of production is requisite. Field screening methods exist that are adequate to estimate contamination levels for aflatoxins. When additional confirmation or quantification is desired, chromatographic laboratory analysis is often necessary. Preparation of matrix samples prior to chromatographic analysis typically requires extraction and purification. Commonly, immunoaffinity columns (IAC), which employ a multi-step bind and elute mechanism to concentrate and purify aflatoxins, are used to purify matrix samples for subsequent analysis. Solid phase extraction (SPE), an alternate method which may use interference removal, can also be employed.

`A technique of growing plants in nutrient solution”. Hydroponics literally means water-working or water-activation. It is a cultivation technique for growing plants in highly oxygenated, nutrient enriched water, rather than soil. The nutrient solution and its management are the cornerstone for a successful hydroponics system. The function of a hydroponics nutrient solution is to supply the plant roots with water, oxygen and essential mineral elements in soluble form. In soil, biological decomposition breaks down organic matter into basic nutrients that plants feed on. Water dissolves these nutrients which allows uptake by the roots. For a plant to receive a well balanced diet, everything in the soil must be in perfect balance.

Modern growing practices include scientific evaluations of soil, water, fertilizers, diseases, etc. While some tests are best performed by a laboratory, others can be easily conducted on location, saving time and money. Three tests in particular, EC, pH, and ALKALINITY, can reveal valuable information about water quality, soil salinity, and fertilizer concentration. MyronL Company’s portable AGRI-METERS provide you with a simple, fast, and accurate means of testing these parameters.

Nicolon Ground Cover Fabrics control weeds found in land maintained by professional growers and landscapers. These highly useful fabrics feature woven polypropylene that allows water and nutrients to pass through while preventing roots from implanting into the soil. Available in widths from 3 to 15 feet (0.90 x 4.5m), Nicolon ground cover fabrics can also be utilized in soil separation and barrier fencing applications.

The Toptex winter protection fabric safely ensures the protection of plants against frost, desiccation and solar radiation.

By TenCate Geosynthetics Netherlands bv based in AE in Nijverdal, NETHERLANDS.

The Toptex fabric is a high grade membrane to protect straw, sugar beet and potato harvests from frost and rain, thereby reducing the amount of clinging clay on beets or potatoes and efficiently leading to less cleaning water needed in the process. On top of this, dried harvests offer a higher yield for the farmer and better quality for the consumer.

The method enables fast quantitative determination in feeds, mixed fodders, and raw materials of the following amino acids: arginine, lysine, tyrosine, phenylalanine, histidine, leucine and iso-leucine (total), methionine, valine, proline, alanine, glycine, cystine, tryptophan, aspartic and glutamic acids. Since during the sample decomposition asparagine and glutamine are hydrolyzed to aspartic and glutamic acids, respectively, the content of these two acids represents the total content of both the acids and the amides.

Introduction

Fungicide Carbendazim (Mercazole, Carbendazole) is widely used in agriculture to exterminate black mold (spot) on orange trees and treat fungus diseases of other fruit-bearing plants. According to the data of the World Health Organization, Carbendazim is toxic for liver, impacts reproductive system, and is considered to be a potentially cancerogenic compound. In most of the developed countries, the residual content of this fungicide is subject to national and international regulations. Researchers of LUMEX INSTRUMENTS, Ltd. have developed an analytical procedure for determination of the Carbendazim content in orange and other citrus juice produce using a capillary electrophoresis system CAPEL-105М.
