Plants That Offer Nutrients
As plants grow, they take up nutrients from the soil, leaving the ground less fertile for the future crops. Gardeners have to replenish the supply by adding the necessary fertilizers or organic matter to the soil to sustain the health of plants.
However, there are certain crops that, in addition to taking nutrients from the soil, also add certain nutrients to it, primarily nitrogen. These nitrogen fixing crops, including beans and other legumes nourish the soil, promoting the growth of their companion crops and future crops that will grow in their place.
Bush beans, pole beans, peas and other legumes make good companions to potatoes since they add more nitrogen to the soil, improving the quality and quantity of the harvest.Read More about Guide to Growing Potatoes 2
