Benefits of organic fertilizer for plants

An invaluable guide to all gardeners and farmers is a soil test. A soil test will indicate when and how to increase applications of fertilizer. First, these tests will show what elements are needed most. Then future tests will show how your fertilizing program is working. With the organic method of gardening, you still need to use the numbers to select the organic materials for your garden.























When you want to add nitrogen to your soil, you can take your pick of manure (fresh or dried), homemade or commercial compost, sludge, and vegetable meals. Due to the high nitrogen content of blood meal and dried blood 12 to 15, these materials should be used more sparingly.

For phosphate, you may choose from rock, bone meal, dried blood, vegetable meals, and manures. Potash sources are granite dust, wood ashes, kelp meal, and many plant residues.

These materials can all be worked into the soil in spring or fall. They can be top-dressed around growing plants, used as a mulch, or added to the compost pile. When you keep a high humus content in your soil, many of these fertilizers will be more readily available. They will also stay available for several years. Organic fertilizers are available at feed mills, farm cooperatives, and local garden supply stores.

Natural mineral fertilizers are considered mainstays of organic gardening and farming. Natural rock fertilizers have been pretty much left out by the average gardener. The average gardener needs to take another look at natural rock fertilizers. They furnish ample supplies of phosphorus and potash, without which no plant can grow successfully. One thing to consider is the fact that natural mineral fertilizers put essential nutrients into the soil gradually over the years so the plants can absorb them as they need them. Because there are no shortages or abundance in the soil, the plants stay in balance, and as the nutrients are released, the soil structure improves.

A Quick Guide to Lawn Fertilizers

If you want to let your lawn look healthy and green, it is essential that you fertilize your lawn. Lawn Fertilizer is one of the most important factors that affect the growth of your lawn. Proper fertilizing provides color and growth to your lawn grass and also helps it to grow thick. Let us take a look at the main constituents of fertilizers. Standard fertilizer contains nitrogen, phosphate and potash. Fertilizing involve the administration of all these constituents but in different amounts. Most lawns would need nitrogen in the maximum amount as it helps in fast growth, gives the grasses darker color and also thickens the grasses. However, you cannot neglect the administration of phosphate and potash. A deficient in phosphate and potash coupled with high dose of nitrogen will result in too much top growth. This can cause insufficient root growth and reduce nutrient storage capacity. A balanced fertilizing program would include all the three constituents in proper amount and micro...

Pros and Cons of Organic Fertilizer

图片
Now, many growers, gardeners and farmers are beginning to understand the need for providing nutrients quickly in order to promote abundant plant growth in gardens and landscapes. Application of nutrients may be accomplished by using either organic or inorganic fertilizer. Due to increased environmental concerns, growers today tend to prefer the use of organic fertilizers over the inorganic type. Traditional fertilizers are known to contain chemicals that may contain concentrated nutrients that may leach and disrupt the soil. It should be noted however, that most people who buy organic fertilizers use them because they believe they are safer for plants. However, if the fertilizer is not applied properly, it can be just as harmful to plants as chemicals are. If not applied properly, they may contribute to ground water pollution, induce salt burn, or cause nutrient deficiencies and soil toxicity. One particular problem that should be emphasized with organic fertilizers is that many of the...

Summer Lawn Care: How to Keep Your Grass Green

图片
It's getting hot out there. And while you might love basking in the summer sun, it can be rough on your grass. So just as you layer on sunscreen before heading out on a sunny day, you must consider summer lawn care so that your grass can stay green all summer long. When the sun grows fiery and passionate in June, July, and August, it beams down sunlight that is both beneficial and harmful to plants. As the days grow longer and hotter, watch out for your grass. We've got just the tips you need to keep your lawn bright, beautiful, and nourished. To begin, you should fertilize your grass. Using a plant food made especially for grass (which means it should be high in nitrogen, which promotes growth and greenness) and a spreader for proper distribution, fertilize your lawn. For best results, wait until the grass is dry and mowed. You want the fertilizer to sink into the ground (if it sticks to the wet blades, it might burn them). When you pour the fertilizer into the spreader, do i...
