| I live in Central Texas a few miles from Austin. The soil is Del Rio clay and Calsecious rock, or caliche. I have been told the soil is iron-poor and to add Ironite to any vegetable bed. I am raising only tomatoes and peppers. Should I "improve" the iron content of the soil as well as the phosphorus and potassium? The soil (when dry) is grey to "dirty white?" |
| and as it breaks down it provides nutrients to the soil. Any organic matter can be used as mulch. Try compost, bark, wood chips, straw, or pine needles.

Follow package instructions. If you prefer organic fertilizers, you may need to use three different sources, since they seldom come mixed together the way non-organic fertilizers do. Side dressings of fertilizer are often beneficial during the growing season, but you shouldn't have to fertilize as frequently as you water. Perhaps once every two weeks at most. As your soil fertility improves, this won't be needed. Examine your plants to see what might be deficient. Slow growth and/or yellowing leaves is often a sign of lack of nitrogen. No flowers or fruit set means phosphorous is missing. Always ensure that the soil is moist before fertilizing, and then water the fertilizer in well afterwards. This helps prevent "burn." If you use a granular fertilizer, scratch it into the soil at least 4 inches to the side of the plant to prevent burning roots. Here's a little background on fertilizers for your info: You probably noticed that fertilizers have 3 numbers on the container. These numbers refer to the percentage of nitrogen (N), phosphorous (P), and potassium (K) in the fertilizer. These 3 elements are referred to as macronutrients because plants need them in fairly large (i.e., macro) amounts to thrive. How these elements interact is complicated but in general terms, nitrogen produces lush green growth, phosphorous helps strengthen stems and produce flowers (and eventually fruit), and potassium keeps the root system healthy. Here are some organic sources of nutrients: Nitrogen: alfalfa meal, blood meal, coffee grounds, cottonseed meal, fish emulsion, seabird guano. Phosphorous: bone meal, rock phosphate Potassium: greensand, seaweed, kelp After planting, add a 1-2 inch layer of mulch.
