Compost manure is a common organic fertilizer, and its quality is essential for agricultural production. In order to ensure that the quality of the compost manure meets the standards, a series of tests are required, including mass fraction of organic matter, total nutrients, pH, moisture, total arsenic, total mercury, total lead, total septum, total chromium, fecal coliform count, and roundworm egg mortality tests. These tests can effectively ensure the quality and safety of the compost.
In the compost quality inspection report, the first thing to pay attention to is the mass fraction of organic matter and total nutrients. Organic matter is an important nutrient component in compost manure, and its mass fraction and total nutrient content are directly related to the value and function of fertilizer. In general, the higher the organic matter content, the higher the nutrient value of the fertilizer, which can provide better nutritional support for plants. Therefore, when testing compost manure, the mass fraction of organic matter and total nutrients need to be rigorously determined and evaluated.
In addition to organic matter and total nutrients, pH, moisture, heavy metals, etc. are also important indicators of compost quality. pH is one of the important indicators to measure the suitability of compost fertilizer for planting crops, and moisture is the key factor affecting the quality and transportation of fertilizer. Excessive levels of heavy metals such as arsenic, mercury, lead, chromium, etc., can have serious effects on the environment and human health, so rigorous testing is necessary.
When performing compost testing, it is also necessary to pay attention to indicators such as fecal coliform count and roundworm egg mortality test. These indicators can reflect the presence of harmful microorganisms and parasites in the compost manure, which is of great significance for ensuring the safety of the fertilizer and preventing plant diseases and pests.
In short, it is very necessary to handle the quality inspection report of the compost, which can effectively ensure the quality and safety of the compost. When handling the quality inspection report, it is necessary to carry out strict testing and evaluation of its various indicators to ensure that the compost can provide effective support and guarantee for agricultural production.
