The availability of flowers which allow bees to gather nectar and pollen from it is known as pasturage. It is a very essential factor which is responsible for the taste and the quantity of honey as well as the production of it.
Crop rotation is a method of crop production that promises a high yield. In this method, a farmer can grow two or more than two varieties of crops on the same piece of land. The plantation occurs in a sequential manner depending on the seasons and the compatibility of crops with those seasons. Every crop utilizes a particular nutrient from the land on which it is grown. In case if the same crop is grown on the land for a continuous time period, the amount of that nutrient is unable to maintain itself and therefore its content depletes in the soil.
Therefore in case of crop rotation, the crops which have different nutrient demands are grown on that land and are rotated. Using this method the nutrient requirement of the crops is met and at the same time, the nutrient balance and maintenance of the soil is also looked after. Using this very method, the requirement for fertilizers is also decreased and the overall production increases in a very profitable manner.
Capture fishing, Mariculture and Aquaculture
