Why do we need variety in daily food?
When we talk about balanced nutrition, it’s not just about the number of calories we consume but about ensuring that our body receives all the essential nutrients. Just like plants need a variety of elements from the soil, such as air, water, and various minerals to grow optimally, we too must meet our daily nutrient requirements through a variety of cooked foods. Each food offers different types of nutrients that the body can absorb, just like how plants absorb different elements from the soil for higher growth and yield. If a plant is deprived of a specific nutrient, its growth is stunted, similar to how our healthier lifestyle is impacted when we lack diversity in our meals. Just like manure and fertilizers enhance soil quality for plants to thrive, having a variety of foods in our diet ensures that we get all the nutrients needed for a well-functioning body. By eating a diverse range of foods, we allow our body to absorb the required nutrients that are essential for energy, growth, and maintenance. So, both plants and humans thrive on variety, but in different forms—plants from their soil and water, and humans from food rich in all the nutrients they need.
Soil Manuring
The process of soil manuring is vital in agriculture, as it helps to restore the fertility of the land, which is often depleted by continuous cultivation. Over time, as crops are harvested, the nutrients and minerals in the soil get used up, leaving it less capable of sustaining healthy plant growth. This is where manure and fertilizers come in as supplements, providing the necessary nutrients that are no longer available in adequate amounts. Farmers use these supplements to ensure that the soil can meet the demands of the plants, especially when growing crops year after year in the same field. Without these supplements, the soil would become weak, and the growth of crops would be hindered, leading to improper or insufficient yields. In some cases, the soil might even become fallow if it cannot produce any longer. By applying manure and fertilizers, we can maintain or even improve the content of essential nutrients in the soil, ensuring healthier crops and a stronger, more productive land for future cultivation.
Manure and Fertilizers
