Name the plant nutrients in fertile soil. How can they be put back when they're used up?.?

Question

Answer plz...it's interesting but I don't quite understand it

Answer 1

Nitrogen, Phosphorus, and Potassium; Calcium, Magnesium, Sulfur; Boron, Chlorine, Copper, Iron, Manganese, Molybdenum, and Zinc. For what each one does, see this site - http://agri.atu.edu/people/Hodgson/FieldCrops/Chapter7.htm

and they can be put back by adding organic matter, which means compost!

.

Answer 2

Ordinary fertilizer that contains Nitrogen, phosporous and potash. or better known as potassium. thats what farmers replace in their soils.

The trace elements are numerous and almost never replaced in the soil. Reports of their depletion is a faulsehood. They are about the same combination in the soil as the original settlers found here centries ago.

Remember, the plant doesnt grow from the soil, the soil merely holds up the plant and furnished water and allows for the processing of the sugars within the plant. The entire plant come from THE ATMOSPHERE.

The air is the source of the all food and you are eating plus some minute sources of trace minerals, the sunlight converts the atmospher into sugars within the plant.

One does not need soil to grow plants. Sure its easier, but they grow in chemical tanks plus sunlight. That is how almost 100% of those tomatoes in the supermarket are grown.

Answer 3

Nitrogen, Phosphorous and Potassium I think (N,P and K) the plants use them along with Co2 and water to grow, their "food", i.e. energy is sunlight, but the nutrients are used and at diff times, (flowering, buds, etc) they need more of one than another. I forget what makes them flower more quickly, etc, but I hope that helps. People can add chemicals directly back into the soil in forms that are water soluble, or if you plant things like Legumes (peas, others I dont know), they I think have rhizomes in their roots that create nitrogen that adds to the soil. But crop rotation is bc if all you plant is corn, it uses up all the stuff corn likes, but if you switch it between crops, they use diff levels of diff nutrients and it is more sustainable. I am no farmer, but i think i have some stuff right.

Answer 4

Fallen leaves do help in making a contribution to the soil yet they take a lengthy time period to decompose if no longer chipped into small products. Egg shells will in all probability draw small animals and insects so that you gained't favor this. one element you should do, with out fairly some artwork, is help the leaves decompose. in the fall even as all of your flora have died, placed a layer of newspaper--about 2-3 newspaper sheets thick--on proper of the leaves. Then use both a landscaping fabrics or black plastic to seem the nice and cozy temperature on the leaves for more advantageous powerful decomposing and also for visual attraction sake. in case you don't love the appearance of the panorama fabrics or plastic, throw a bunch of stones or mulch on proper. For a million years, flora were fed with assistance from the laying off of their personal leaves. even if it takes time. with assistance from putting newspaper and mulch over them, it facilitates % up the approach. and also you're also doing a strong element for the earth with assistance from permitting the flora to feed themselves with assistance from laying off leaves and permitting them to decompose and feed your flora the subsequent 3 hundred and sixty 5 days.

Answer 5

The main plant nutrients are nitrogen.phosphorous and potassium. Plants need minerals as well. Organic amendments would be: Manure, earthworm castings, bloodmeal for nitrogen,bone meal for phosphorous and potash for potassium. Kelp is good for minerals

Answer 6

How about looking the answer up yourself? That is the purpose of homework! If you can't even understand the question, I think you had better start doing your own homework!

Answer 7

Plus N2, O2 and H20

Answer 8

IRON AND LIME ARE 2 MOST KNOWN...AND YOU CAN BUY THEM TO REPLACE IN SOIL AT WALMART OR MOST NURSERIES
