The method is used for the determination of the mass fraction of all primary and secondary nutrients (macronutrients) in fertilizers by capillary electrophoresis. The method allows the determination of such macronutrients as ammonium nitrogen (ammoniacal nitrogen, NH4-N), nitrate nitrogen (NO3-N), phosphorus (P or P2O5), potassium (K or K2O) as well as sodium, magnesium, calcium, sulfur, chlorine (chloride), fluorine (fluoride).

Ammonia is a notoriously difficult compound to measure accurately and reliably using standard chemical sampling techniques. The great advantage of the optical laser gas detection technique for quantitative ammonia monitoring is that the optical measurement does not affect the air being sampled – and so a true, undisturbed value for ammonia concentration can be determined. The very high resolution and specificity of the laser method also means that is no interference from other gases in the air (for example, water vapor) – such interferences complicate other optical techniques using IR or UV.

Process control and emissions monitoring in a fertilizer plant is a challenge due to the high concentrations of HF. To use an extractive system in this environment will demand a lot of maintenance.

Recycling carbamate solution back to urea-reactors (Stamicarbon- and Snamprogetti-Processing Methods) will be done world-wide more or less exclusively with Körting high-pressure liquid jet ejectors (H.P.-ejectors). Multi-stage steam jet vacuum systems specifically designed to meet the requirements of urea evaporation stages have been in use for many decades now with great success. New developed boosters and vacuum condensers are available to provide an extremely economical and trouble-free operation.

Subsurface drip Irrigation Systems (SDI) are a suitable agronomic option for all type of crops: woody crops (almond tree, vineyard, olive tree, pistachio tree, peach tree, etc.) and extensive crops (corn, vetch, barley, alfalfa, etc.). The SDI is an irrigation technique that allows the supply of water and nutrients in a localized way under the surface. This fact conditions and optimizes the growing of roots and the development of the plant. This practice makes possible a more efficient use of the water, energy and fertilizers, becoming the alternative with best results from an economic, agronomic and ecologic point of view.

Precision agriculture is no longer a new term in crop production. It is now a widely accepted practice. Aerial imagery is a key component in utilizing precision agriculture techniques for the management of farmland. The GeoVantage Imaging System provides high-resolution, orthorectified images that are used by Cooperatives, Ag Service Providers (ASPs), Crop Consultants, and Growers to:
- Create management zones
- Evaluate the effectiveness of fertilizer applications
- View the whole farm/field
- Perform in-season analysis to make crop management decisions
- Manage geo-referenced soil sampling
- Precisely schedule irrigation
- Scheduling of pesticide applications
- Find mechanical errors in application equipment

Hydraulic Erosion Control Products (HECPs) are engineered mulch applied to slopes to reduce soil erosion while assisting in the establishment and growth of vegetation. An alternative to temporary Erosion Control Blankets (ECBs), hydraulically applied products can be installed up to three times faster using one-third the manpower. North American Green`s HECPs are applied in a one-step application with seed and fertilizer, with the potential for quicker installation and project cost savings compared to products requiring a two-step application. With our selection of HydraMax Systems HECPs, we can help you comply with the Environmental Protection Agency’s (EPA) effluent guidelines.

Intensive commercial shrimp farming began in the late 1960s led in part by technological advances and growing market demand. Today, shrimp farming is so intensive (in some cases close to 300 000 shrimps per hectare) that it requires industrially prepared shrimp feeds, fertilizing the ponds to stimulate the growth of organisms, aeration to prevent oxygen depletion and regular tidal water exchange. Solmax geomembranes have been used in some of the largest shrimp pond projects in the world. There are several key benefits of lining shrimp ponds with geomembranes. Durable and robust, the HDPE surface prevents weeds, grasses, mud and other obstructive contaminants from entering the pond. The HDPE substrate is known to reduce the suitability of the environment for bacteria thereby reducing the need for antibiotics. Geomembranes can also protect the slopes and banks from erosion and allow for easy detection and rapid removal of sediment and waste products.
Here are several factors to consider when deciding which type of geomembrane to use in a Shrimp Pond application:
- Stress crack resistance
- Tensile and elongation properties
- Tear and puncture resistance
- Duration of the project
- U.V exposure

TeraFlo® significantly reduces watering requirements per cycle of irrigation while maintaining adequate moisture for good plant health and growth. Due to its filtration properties, excessive moisture also flows through the soil thereby preventing environments for fungal growth. It draws moisture from the air and the surface and attaches itself to the plant roots from sources not previously available. It provides proper wetting and drainage in non-soil media as well as eliminating unusable water. TeraFlo® dramatically improves the ability of rainfall and water to easily penetrate the soil surface and gain access to the root zone. By encapsulating the soil particles, it significantly decreases friction allowing for easy and rapid water penetration and filtration into any soil condition; hardpan, compacted or otherwise. It improves the efficiency of all applied additives (pesticides, insecticides nutrients, etc) preventing rapid leaching of these products. This increases their effectiveness and reduces over all application quantities making additive usage far more cost effective. Holding organophosphates in the soil reduces the leaching of these toxins which significantly improves their performance. The product has a special affinity to nitrogen thereby reducing nitrate leaching protecting against groundwater contamination. TeraFlo® prevents the buildup of soluble sodium salts contained in fertilizers and water sources thereby reducing stress conditions. Continual use will keep the root zone free of sodium salts. TeraFlo® increases microbial activity which aids in root cell buildup resulting in faster uptake of nutrients. TeraFlo® reduces soil erosion from in-furrow irrigation and significantly reduces nitrogen loss in head ditch irrigation systems. TeraFlo® improves drip applied fumigant systems allowing for a more efficient and longer release system. Teraflo provides lubrication to pump parts, valves, and other parts of pressurized water systems preventing products in the irrigation piping from sticking to the walls, thus reducing drip and irrigation head clogging. This reduces downtime, repair costs, and maintenance.
