Nutrient deficiencies and fertiliser requirements are assessed through routine analysis of agricultural soils and soil additives for chemical and physical parameters.
Understanding Soil Sample Analysis
Every area is different when it comes to soil types and nutrient contents in soil. Soil sampling and testing can show you the plant available nutrients and other soil chemical factors important for winter wheat production. Nutrient levels in soil also vary from year to year, so it is important to perform soil sampling and testing prior to planting any new crop. It is important for farmers to follow certain recommended steps for soil sampling and testing to develop a fertility management program. To ensure accurate results, standards must be set for performing soil sampling and testing. Here are some guidelines set out by Alberta Agriculture:.
Soil nutrient testing
Soil test may refer to one or more of a wide variety of soil analysis conducted for one of several possible reasons. Possibly the most widely conducted soil tests are those done to estimate the plant-available concentrations of plant nutrients , in order to determine fertilizer recommendations in agriculture. Other soil tests may be done for engineering geotechnical , geochemical or ecological investigations. In agriculture , a soil test commonly refers to the analysis of a soil sample to determine nutrient content, composition, and other characteristics such as the acidity or pH level. A soil test can determine fertility , or the expected growth potential of the soil which indicates nutrient deficiencies, potential toxicities from excessive fertility and inhibitions from the presence of non-essential trace minerals. The test is used to mimic the function of roots to assimilate minerals. The expected rate of growth is modeled by the Law of the Maximum.

A soil test is important for several reasons: to optimize crop production, to protect the environment from contamination by runoff and leaching of excess fertilizers, to aid in the diagnosis of plant culture problems, to improve the nutritional balance of the growing media and to save money and conserve energy by applying only the amount of fertilizer needed. Pre- plant media analyses provide an indication of potential nutrient deficiencies, pH imbalance or excess soluble salts. This is particularly important for growers who mix their own media. Media testing during the growing season is an important tool for managing crop nutrition and soluble salts levels.
There are several components to sound soil testing programs, namely: 1) proper collection and care of the sample, 2) appropriate test procedures, 3) well.

Soil sampling, processing and storage Soil sampling Principle Soil testing is an essential component of soil resource management. Each sample collected must be a true representative of the area being sampled. Utility of the results obtained from the laboratory analysis depends on the sampling precision. Hence, collection of large number of samples is advisable so that sample of desired size can be obtained by sub-sampling. In general, sampling is done at the rate of one sample for every two hectare area.
Soil fertility test kits may be purchased from county offices of Penn State Extension or from commercial firms or garden centers that stock kits for the convenience of their customers. The test kit consists of a sample submission form, instructions on how to take a soil sample, a sample bag and return envelope for mailing your sample back to the laboratory.
- Хейл в Третьем узле. Он напал на. - Что. Этого не может. Он заперт внизу.
Конец веревочки. Он набрал номер. - Escortes Belen, - ответил мужчина. И снова Беккер изложил свою проблему: - Si, si, senor. Меня зовут сеньор Ролдан.
- Мой человек ликвидировал его, но не получил ключ. За секунду до смерти Танкадо успел отдать его какому-то туристу. - Это возмутительно! - взорвался Нуматака.
