Find out everything you need to know about it here. Simply so, is Phosphorus good for tomato plants?
Why Tomato Plants Need Phosphorus Phosphorus is one of the Big Four macronutrients that tomato plants need in order to be healthy – nitrogen (N), phosphorus (P), potassium (K), and calcium (Ca). Each of these nutrients has a specific role in growing healthy plants. In simple terms, phosphorus is a converter.
One may also ask, what nutrients do tomatoes need most? Nitrogen, phosphorus and potassium, known as "primary nutrients," are the three main ingredients in most fertilizers and are vital to tomatoes. Plant growth and chlorophyll production depend on nitrogen, and phosphorus helps tomatoes grow and cope with stress while aiding in energy production.
Likewise, people ask, how much phosphorus do tomatoes need?
Growers might get away with growing tomatoes in soil that's too acid for something like spinach.” Tomatoes typically need a lot of potassium. Recommendations call for up to 225 pounds per acre. Phosphorus requirement is about 150 pounds per acre and nitrogen application rate would be 100 pounds per acre.
What is a good source of phosphorus for plants?
If you can find them, fish bone meal and soy husks are other good sources. And then there is compost :-) Composted yard waste and manures generally provide all the phosphorus normally required by most plants in most soils and if applied in excess, can create an oversupply.
