When manure and nitrogen are not managed properly they directly contribute to greenhouse gas emissions and as the livestock industry grows the waste from these animals degrades the environment because of the methane that is released from the manure as it decomposes. All of this contributes to global warming. It also puts additional pressure on larger commercial greenhouse operations.
But there are many solutions being used to help farmers manage manure and reduce the overuse of fertilizers. In fact there are systems being developed to help turn these potentially dangerous waste materials into a useable product for the greenhouse industry. An interesting idea that is innovative and promising.
One of the keys is to learn to use nutrients more effectively and more efficiently so that the amount of waste is reduced and the benefits are increased
The fertilizer program you should use will depend on what crop you are dealing with. There are different approaches for different crop types and you may need to do some fine tuning depending on where your greenhouse is located.
You will need to consider the appropriate ratio of ammonium to nitrate and the actual fertilizer type that is best for your crop. Calcium and magnesium can change the acidity of your crop's soil. Although traditional fertilizers are commonly used there are many new alternatives that you should explore.
How often you need to apply the fertilizer depends on the type of fertilizer. Water soluble fertilizer is important in developing a good program.
Constant liquid feed is often referred to as CLF and what it refers to is the scheduled reoccurrence of the application of the fertilizer whether that be weekly, daily, or even monthly. The more often it is applied the higher the fertility level of your crop.
As you increase the volume of the fertilizer which is water soluble the nutrient level also increases often doubling the potential nutrient value to the plants.
When you fertilizer you must remember that some leaching does occur and that not all the fertilizer actually makes it to the plant you are fertilizing. The plants growth rate will be directly affected by the type and number of fertilizer applications.
Each type of crop has its own specific requirements which can readily be found on line. One article is simply not long enough to provide a detailed breakdown.
What is important to remember is that the correct fertilizer application is important to ensure your maximize your crop. For example many flowers will require an entirely different fertilizing regime than vegetables such as carrots or onions might need.
Knowing these differences and dealing with them appropriately will ensure that you have healthy fruits and vegetables and beautiful flowers that are all profitable to your business.
Greenhouse fertilization is one of the most important elements to your profit margins.
