Nitrogen.
Because peas and beans are legumes, plants which fix nitrogen, an essential plant nutrient, in the soil for the next crop cycle.
Some plants, such as beans, put nitrogen, an incredibly essential nutrient, back into the soil, whereas others do the opposite. Also, they can prevent erosion.
Many crops deplete essential nutrients from the soil, such as nitrogen, phosphorus, and potassium. Continuous farming of the same crop can lead to nutrient depletion in the soil, which may require fertilizers or crop rotation to replenish the nutrients.

Beans grow faster in soil than water because soil provides a stable and nutrient-rich environment for the plant to grow. Soil also allows for better aeration and root development, which are essential for healthy plant growth. In contrast, growing beans in water may lack essential nutrients and oxygen needed for optimal growth, leading to slower development.
The plant environment, specifically soil pH, affects crop production by influencing nutrient availability. Different crops have varying pH requirements for optimal growth and nutrient uptake. Soil pH also affects the activity of soil microorganisms and influences the solubility of essential nutrients. Maintaining the appropriate pH level is crucial for maximizing crop yields and overall plant health.
Soil profile is essential for farmers as it provides valuable information about the characteristics and fertility of the soil. It helps farmers make informed decisions regarding crop selection, nutrient management, irrigation, and soil conservation practices. Understanding the soil profile can lead to higher crop yields and overall farm productivity.
crop rotations give the soil a break from having to support the same crop which drains the soil of the nutrients. Eventually the slil is deprived of the nutrient and the plant will no longer grow there.
Planting the same crop every year in the same soil can deplete essential nutrients specific to that crop, leading to nutrient imbalances in the soil. It can also increase the population of soilborne pests and diseases that target that particular crop, potentially reducing yields over time. This practice can also disrupt the soil's natural ecosystem, decreasing its overall health and resilience.
To calculate the fertilizer requirement on a soil weight basis, you need to first determine the nutrient content in the soil through soil testing. Once you have this information, you can calculate the amount of fertilizer needed to correct any nutrient deficiencies or meet crop requirements based on the recommended application rates. This calculation takes into account the desired nutrient concentration in the soil, crop nutrient uptake, and fertilizer nutrient content.

Crop rotation helps soil fertility by reducing nutrient depletion and pest buildup. Different crops have varying nutrient needs, so rotating crops helps maintain a balanced nutrient profile in the soil. It also disrupts pest life cycles, reducing the need for chemical pesticides and promoting a healthier soil ecosystem.
