What is whey and how is it made?

Please note that there is a difference between sour whey and sweet whey: sweet whey comes from cheese that is made with rennet. Sour whey is a by-product when we make dairy products that do not require rennet - yogurt, buttermilk, kefir, etc.(There is a subcategory of sour whey called "boiled whey", which is left over from the preparation of Paniru, Queso Fresco and Ricotta. Contains less protein and fewer vitamins and minerals than other whey, but you can still use it in your garden.

A lot of information found on websites or books incorrectly recommends using only sweet whey, not sour whey, in gardening. This is based on the assumption that you can pour a liter of acid whey into a tomato regardless of its acid content. This is not the best solution for your plants. In fact, some people pour acid whey over their weeds to exterminate them! Both types of whey can harm the environment when large amounts are dumped into water bodies, as changing the pH of the water affects, for example, fish and other organisms that inhabit the water.

Organic seeds for sowing are better and he althier than traditional ones!

Whey - an ecological solution to powdery mildew

Whey actually contains small amounts of nitrogen, phosphorus and potassium (as well as calcium and magnesium). The N-P-K ratio is usually 0.15-0.05-0.17. (Sour whey has less protein than sweet whey, but still contains many of the same vitamins and minerals as sweet whey.) This is low enough to use regularly without fear of over-fertilizing.

Application instructions:

1. Drain the whey in gauze or butter so that no large chunks of cottage cheese float in it.
2. Dilute before adding to soil. First, dilute it with the same amount of water to get a 50:50 split.
3. Pour the fertilizer around the base of your plants, not over the plant parts themselves, including leaves and stems.
4. Try not to give your plants a total of more than 1 diluted whey per week. (You will need a meter for this.) A common recommendation is to use 1 liter of diluted whey per 10 square meters of garden area every 7 to 14 days.
5. For powdery mildew spraying, simply put the whey into a sprayer and dilute it with water or mix it with nettle slurry to enhance the effect.
6. We water the infected areas once a week to fight the mildew.
