Question

Farmers apply manure to the plants. How do nutrients reach the plant​

Answer 1

Explanation:

One of the best ways to use manure as plant fertilizer is by mixing it in with compost. Composting manure eliminates the possibility of burning the plants. Another option is to till it into the soil prior to spring planting, such as during fall or winter. Generally, fall is the best time to use manure in the garden.

Answer 2

Answer:

Manure contains valuable plant nutrients, like nitrogen (N), phosphorus (P), potassium (K), and sulfur (S). Manure nutrients come from the feed that the animals have eaten. In fact, most of the nutrients that animals eat end up in their manure. For example, more than 75% of the nitrogen and

ore than 65% of the phosphorus that a steer eats will be passed into the manure.

Most of the nutrients that animals eat end up in their manure.

The amount of nutrients in manure depends on the type of manure and how it is handled. Poultry manure contains the greatest amount of nutrients, while horse manure has much less nutrients (Table 1). Manure that contains lots of bedding will have fewer nutrients per pound than pure manure.

Poultry manure contains the greatest amount of nutrients.

Forms of Manure Nutrients

The nutrients in manure are a mixture of inorganic and organic forms. Many of the inorganic nutrients in manure are the same as those in a commercial fertilizer. These nutrients include ammonium nitrogen, soluble phosphate, and potassium salts. They dissolve in water, and plants can use them right away.

The organic forms of nutrients come from the remains of plant tissue, cells, and bacteria that are in the manure. They are called slow-

release nutrients because plants cannot use them immediately. These slow- release nutrients become available to plants as the manure decays in the soil and releases the nutrients.

Liquid manure and solid poultry manure contain large amounts of inorganic nutrients, especially nitrogen, that dissolve easily. Most of the nitrogen in other solid manures is organic and is slowly released.
