What is one man’s garbage;
Is another man’s treasure.
Wouldn’t you want great looking grasslands like this:

Use manure!
Most of us think of manure as, disgusting, stinky, repulsive, so on and so forth. On the other hand, farmers treasure manure, especially from cows. Whether we believe it or not, science can prove that manure contains many essential elements for grass to grow. Most of us probably think that manure contains all the bad things our body is trying to get rid of, but in reality, manure contains everything our body no longer needs including things that are perfectly good.
Manure contains mostly N, P2O5, and K2O. It also contains very small amounts of calcium, magnesium, salinity, zinc, iron, manganese, copper, sodium, sulphur, and boron. To obtain healthy great looking grass and crops, you require mostly nitrogen, phosphate and potassium.
N + P2O5 + K2O = healthy, great looking, green grass and crops
Fertilizer is used to make the soil rich and fertile, it allows the crop and/or grass to grow faster and healthier; in other words, fertilizer is a catalyst used in this chemical reaction. There are mainly two sorts of fertilizers, organic and non-organic. Manure; is organic and works extremely efficiently. You also obtain a lower pH level with organic fertilizer. Low cost and easy to produce.
Hay/food à cow/pig/any farm animal à manure à grass/crops à $$$
The farmer has to feed the cow and the end result will big money. Cow manure is not the only great manure, other animals have good manure, but possibly not as great. So
remember, the next time someone takes a dump on your front lawn; thank them.
