Frequently Asked Questions

What is the difference between orthophosphate and polyphosphate and is one better than the other?

Orthophosphate is a single phosphate molecule. Polyphosphate is a chain of orthophosphate molecules. When polyphosphate is in the orthophosphate form, it can be taken up by the crop or tied-up by the soil. Polyphosphate molecule chains must hydrolyze (or break apart) into separate orthophosphate molecules in order to be plant available. However, the poly chains will convert to ortho after they are applied to the soil.
Research shows that all added polyphosphate is typically hydrolyzed to ortho within days from soil application, and is enhanced by warm soil temperature, moisture content, soil pH and biological activity. Water-soluble poly products convert to ortho more quickly.

How can I get fertilizer samples to try out?

What type of fertilizers do farmers use and why?

Farmers use different fertilizers based on the plant they are growing because each plant or crop has a varying level of nutrient requirement and understanding the differences in the needs of plants is very important while fertilizing the crops. The major type of fertilizer used by most of farmers is the NPK type chemical-based fertilizer. Other than this, farmers also use organic or natural fertilizers if they are growing organic food or if the plant or if the plant exclusively needs organic elements.

Does AG Pro Organics use organic fertilizer products?

Yes, we use products are listed by OMRI, CDFA, and WSDA, and meet the National Organic Program requirements for certified organic production.

What is the difference between manure and fertilizer?

The major differences between fertilizer and manure are:

Fertilizers are man-made and are prepared in factories whereas manure is a combination of inorganic and organic substances.
Fertilizer can provide the exact amount of nutrients to the plants, but manure has a mixture of all nutrients because they contain organic elements which occur naturally in nature.
Fertilizers have high nutrient concentration and manure has a low concentration of nutrients.
Humus is provided by manure and not by fertilizers.
