Homemade Fertilizers for Grass

Grass requires a high concentration of nitrogen to grow to its full potential. Nitrogen is common in household products and food, so there are many ways to make effective lawn fertilizers. However, if certain homemade fertilizers are applied during the wrong time of year, a burned lawn can result. To that end, you must always take care to apply fertilizer to your lawn in a thin solution and only during the rainy season.

Soda Fertilizer

Grind a handful of eggshells into powder. Mix with 1 can non-diet soda, 1/2 cup liquid soap (no anti-bacterial soap), 1/2 cup ammonia, 1/2 cup vinegar, 1 cup fresh yogurt culture and 1/2 cup mouthwash. Dilute the mixture in several gallons of water and leave to sit for a day before spraying across the lawn. The eggshells will be dissolved by the acidity of the vinegar into their component calcium carbonate (calcium being of secondary use to grass). The liquid soap aids in proportional dispersal of the mixture and keeps it clinging to the grass. The yogurt culture provides the bacteria and the soda provides the sugar to convert the ammonia into nitrogen.

Apple Juice Fertilizer

Combine 2 tbsp. coffee grounds with 1 cup orange juice, 1 cup apple juice and 2 cups liquid fabric softener. Let this sit for several hours before diluting in 5 gallons of water. Normal water will do but water from a freshwater aquarium tends to have a good amount of nitrogen as well as some potassium and phosphorous--all three very important for any plant's growth. The acidity of the combined juices and coffee grounds acts upon the liquid fabric softener, which is composed primarily of ammonium salts. These ammonium salts are only stable because the liquid fabric softener has a very high level of alkalinity. By countering this with acids the ammonium, salts break down into nitrogen and oxygen.

Beer Fertilizer

Mix 1 cup beer, 2 cups water, 1 cup ammonia and 1 cup Epsom salts and sprinkle over roughly 500 square feet of lawn. The microbes and yeast present in beer act to break down the ammonia into nitrates. Simultaneously, the Epsom salts also break down. Normally Epsom salts are made up of oxygen, carbon, calcium and magnesium in a crystalline molecular structure. Carbon, calcium and magnesium are all good nutrients for grass, while the release of the oxygen in a fizzing action serves to aerate the lawn and make it more readily able to absorb these nutrients.
