Ferrous sulfate heptahydrate can be safely used in home garden. It is a green product which no harm to Soil and plants. Ferrous sulfate contains the elements of iron and sulfur. Iron is more readily available to plants when the soil pH is below 7, as alkaline soil binds iron particles and makes them unavailable absorb for plants. If your soil is too alkaline, application of ferrous sulfate heptahydrate can lower the PH.
Most of plants require a more acidic soil than our natural soils, so we have to add iron sulfate heptahydrate or call it ferrous sulfate heptahdyrate to the soil to for the plants to grow properly. The best PH in soil for plants is between 6.0 and 7.0. To satisfy these acid-loving plants, it is necessary to test the present soil conditions before adding anything to the soil. Make sure adding how much product to get desire PH.
Testify your soil's PH level is one clue to your soil's potential to provide nutrients for plant health. However, the shortage of iron often occurs in alkaline soils. Fe deficiency caused yellow leaves; leaf yellowing from iron deficiency is distinguished by where the yellowing begins. Ferrous sulfate is a green product which can effectively change soil Ph and prevent crops from Fe deficiency.
The fastest way to improve soil condition and Fe deficiency is to spray a solution of ferrous sulfate over the area. After spray solution, the plants will reacts at 3-4 weeks. Please make sure each time you not over spray, unless it will burn the leaves. Although, Ferrous sulfate monohydrate granular woild also work, the iron in these does not always break down so that it is readily available to the plants, and the effect of use granular will slower than spray the solution.
