soil depletion
Different crops use different nutrients in the soil. Crops are alternated so not all the soil's nutrients are used up before nature can replenish them.
In true organic farming, the soil is built up with organic matter, which means nutrients in the soil are replenished. In non-organic farming, fertilizers are used to replenish certain nutrients only, while other nutrients may be depleted. In that sense, soil (nutrients in the soil) last longer in organic farming.
because when a plant lives it draws nutrients out of the soil through it's roots to live, leaving less nutrients in the soil meaning there are less nutrients for other plants to grow at a later time. so to ensure future plant growth, you must replenish the nutriens.
Fertilizer can be a composition of man made and natural nutrients combined to replenish the soil nutrient deficiency. Where manure is natural nutrients from animal feces.
if the farmer do not replenish the soil the crops will damage.
There are different types of fertilizers, and some ways of replenishing nutrients to the soil are much better than others for the growth and nutrition of the plants and for the environment. One type of fertilizer is synthetic. These are the N-P-K fertilizers that only replenish the nitrogen, phosphorous, and potassium, but not other nutrients and micro-nutrients that plants need. They may contain ingredients that pollute the environment. Another way to replenish nutrients and to develop good soil generally is to add compost and natural materials to the soil. This not only builds up the soil and replenishes the micro-nutrients as well as nitrogen, phosphorous, potassium and other nutrients, but is safe for the environment. So, fertilizer may be considered bad because it does not replenish all the nutrients and micro-nutrients that plants need and it may pollute the environment.
I would like to replenish my yard. Farmers replenish the nutrients in their soil by rotating crops. Mosturizing helps replenish your skin. She will replenish her dog's bowl when it is empty. The military replenishes supplies as they are consumed in battle by troops. The forest was replenished by the rainfall. We must find alternatives to oil as it will not replenish itself.
may gradually replenish soil nutrients and potentially reduce the flow of agricultural pollutants to nearby water sources, according to findings by Agricultural Research Service (ARS) scientists and colleagues.
Mole helps to mix the soil in their process of moving . This activities allows the soil macro and micro nutrients to be mixed and nutrients are also formed through their waste materials which help to replenish the soil,roots penetration,water drainage,disentigration of rock etc.
