Certified Testing Laboratories (manure & soil)

When evaluating the necessary amount of field fertilizer, it is useful to know the amount of soil and fertilizer. A plan was developed to certify the laboratory that provides the exam

Fecal analysis is strongly recommended to help farmers understand the value of fertilizer applied to crops rather than commercial fertilizers. If manure is used instead of commercially available fertilizer, yield of normal crops will increase, but accurate analysis of manure is indispensable.

In the soil survey, we collect soil samples for laboratory and engineering testing as needed. Laboratory data from similar soil from other places was collected. Data on crop yields for specific practices were obtained from farm records and field trials or plot tests for the same soil. Estimate all soil definition management yield. However, a part of the soil survey is named on the soil, is described on the map, and is executed only when it is drawn, and laboratory data and yield data are summarized. Next, we need to organize many detailed information so that it can be useful for various user groups such as farmers, farm managers, engineers, home owners, etc.

Various laboratory tests can be performed on the soil to measure various soil properties. Some soil properties are inherent in soil matrix components and are not affected by sample interference, but other properties depend on soil structure and composition, effectively only in relatively confusing samples I can test it. Several soil tests measure the direct nature of the soil, while other soil tests measure "exponential properties" and provides useful information on the soil without directly measuring the desired properties.

Many disturbed and undisturbed samples should be removed from each layer encountered in the borehole. Soil samples provide materials for studying soil properties through laboratory tests The results of soil investigation should be detailed in the report (Terzaghi, 1967). In this section, we will discuss the location, the method of drilling and sampling, on-site field tests, laboratory test results, acceptable support and settlement, the groundwater level should describe its habitat in detail. Variations to be made, and the amount of soluble salts or other minerals present, and considerations for building foundations and levees
