If you do use this fertilizer, be very careful, as you could damage your plants. Here are some
recommended articles and sites.
N-P-K (Nitrogen- Phosphorus- Potassium) are the 3 most abundant ingredients listed on EVERY fertilizer label. They are always in this order, N-P-K. You will see them on the label as three numbers.Such as: 30-10-10 / 10-5-5- / 21-0-0- But what does it mean and how do you know which formula you need? The first example, 30-10-10, means that if you had 100 pounds of that fertilizer there would be 30 pounds of available nitrogen, 10 pounds of available phosphorus and 10 pounds of available potassium (potash). The remaining 50 pounds are inert or inactive ingredients.
Do not fertilize plants in the hot sun. This can cause leaf burn and damage the plant.
Do not fertilize plants when the soil is dry. This can cause the roots to get damaged, alaways make the soil is moist.
Most seedlings do not benefit from fertilizer use. Wait until you feel the plant is old enough (3-4 weeks) to safely apply any fertilizer. When starting to fertilize very young plants do so sparingly.
Your tomatoes need a proper "balance" of nutrients. Packaged fertilizer should include on its label the Nitrogen, Phosphorous and Potassium ratio of 5-10-10 or 10-10-10.
For best results, stay with these numbers; since, a change from the stated numerical format like 20-5-5 [too much nitrogen] will create tall, very green, leafy tomato plants with little or no tomatoes.
Fertilize every two to four weeks. Fertilizers high in nitrogen will result in a leafy, green plant at the expense of root development. A good fertilizer for sweet potatoes and yams contain low levels of Nitrogen, and high levels of phosphorus. 6-24-24, or 8-24-24, are good fertilizers for sweet potatoes.
Fertilization
Sweet corn grows best at a soil pH of 6.0 to 6.8 (soil acidity/alkalinity) and with a good supply of nutrients. Wellaged manure or compost incorporated into the soil before planting will provide nutrients and increase waterholding capacity. Generally, corn needs a nutrient supply equal to the application of about 25 pounds per 1,000 square feet of 10-10-10 fertilizer (this is about 1,000 pounds per acre). Equivalent rates of other analyses such as 15-15-15, 20-20-20, etc., or organic
