What's the NPK of your BYM? (nitrogen, phosphorus, and potassium content of barn-yard manure)
Plants need carbon dioxide from the air for photosynthesis and oxygen for respiration. 植物需要空气中的二氧化碳进行光合作用,也需要氧气进行呼吸。 Nutrients 营养 Plants require essential nutrients like nitrogen, phosphorus, and potassium, which...
hydrogen, oxygen, nitrogen and phosphorus atoms, joined together to form a large molecule. There is nothing that special about the atoms found in a molecule of DNA: they are no different from the atoms found in the thousands of other molecules from which the...
Soils have a great capacity to filter and remediate pollutants, but applications of pollutants to soils often exceed this capacity. When we apply excess nutrients to soils, particularly nitrogen and phosphorus, we make these soils sources of nutrient pollution to water bodies. These nutrients can ca...
Most of the organic constituents of plants are formed of carbon, hydrogen, oxygen, nitrogen, and occasionally phosphorus, sulphur and selenium. No organic halogen compounds have been found in the higher plants ; there is no sound evidence that iodine or bromine is necessary for plants, nor is ...
Step-by-Step Text Solution:Step 1: Define Eutrophication Eutrophication is the process by which a water body becomes overly enriched with nutrients, particularly nitrogen and phosphorus. This often results from
But nitrogen is an unstable element. It can be washed out when it rains or it can be released to the atmosphere, whereas phosphorus combines with calcium and iron, and can be preserved in the soil for thousands of years. The soil from the Botai settlement sites was found to have high co...
Explain how the phosphorus and nitrogen cycle works Which element is playing an important role in nitrogen fixation? What is the nitrogen cycle? Explain the steps. Explain the nitrogen cycle with examples. (a) Describe nitrogen fixation. (b) Why is it important to agriculture?
Explain how water is recycled by the hydrologic cycle and how human activities can interfere with this cycle. Explain how decomposition affects the rate of nutrient cycling in ecosystems. Explain the steps of the water cycle. Describe the carbon, nitrogen, phosphorus, and sulfur cycles, and explai...
FEMALE PROFESSOR: Good question, George.You’re right to guess that phosphorus can end up in Earth’s atmosphere …it can move from the land or from the oceans to the atmosphere, and vice versa.However, there’s just not a substantial amount of it there, like there is with nitrogen.It...
