In order to select a liquid fertiliser for your crop, it’s important to understand what ingredients you should look for, what applications are suitable for it and how to store it properly. Read on to learn about the different ingredients, their bioavailability and storage options. We’ve also outlined some of the common risks when using liquid fertiliser. Once you’ve found the right product for your crop, you’ll be well on your way to growing healthy and thriving crops!

Ingredients

One of the most important factors when choosing a liquid fertilizer is the type of material that it contains. The organic liquid fertilizer will contain a combination of minerals, water, and organic matter. This mix will be rich in nutrients and can be diluted for use on gardens. The organic liquid fertilizer was introduced to trainers of ECHO’s rural programme in the rural regions through workshops and forums. The method of making it involved preparing the raw materials for use. Generally, it required a container, ingredients, and a stick to mix the solution.

Liquid fertilisers contain higher levels of active ingredients than their dry counterparts. While the proprietary chemical composition of liquid fertilisers may vary, they all contain a few key ingredients. Understanding these ingredients will help you select the best fertiliser for your garden. A typical quart of 3-3-3 liquid fertilizer contains 0.08 pounds of nitrogen, 36 grams of P2O5, and 108 grams of potassium per liter. The remaining 1089 grams of the mixture are water.

Applications

For healthy plants, regular applications of liquid fertiliser are essential to promote growth. Liquid fertiliser helps increase flowering and fruit production of annuals and perennials. Applying liquid fertiliser weekly through a drip line will promote early spring growth and promote reduction of nitrates in plant tissues by late summer. The application of liquid fertiliser must be based on petiole analysis, sampled at veraison and cleaned with distilled water.

Bioavailability

Bioavailability is an important consideration in organic vegetable production as nitrogen availability in the soil is limited. This often requires additional nitrogen fertilization. Furthermore, the widespread use of drip irrigation has increased the demand for liquid organic fertilizers. We evaluated the nitrogen availability of three liquid organic fertilizers: Phytamin 801, Biolyzer, and DMSO-free. The N content of these products varied significantly (from 26 to 60 g*kg-1), but all of them had high levels of particulate matter that was removed by filtration in drip irrigation systems.

The pH of liquid organic fertilizer should be adjusted to 2.5 to 4.0 using non-synthetic acetic acid from the sugar or fermentation industries. This step improves the storage stability of highly nutritious liquid organic fertilisers and reduces their susceptibility to microbial attack. plant food However, this method has a drawback. The cost of organic liquid fertilisers varies widely, from $13 to $18 per kilogram of N. For the same amount of N, you can purchase other organically approved sources of fertiliser at lower prices.

Storage

For the storage of liquid fertiliser, the Labaronne-Citaf tank range is an excellent choice. Developed for the agricultural sector, this range of tanks meets the strict requirements of the European regulatory framework for health and environmental protection. It is ideal for storing nitrogen and sulphur solutions. This versatile range of tanks is available in various capacities and can be customised to meet the specific needs of farmers. Read the safety data sheet before purchasing any tank.

Generally, a poly tank containing liquid fertiliser should be of 1.5 or higher specific gravity, as these are denser and stronger. The specific gravity of a tank refers to the plastic resin per square inch of its surface, and a higher number means a denser container. It is recommended that tanks be bunded to prevent the spread of a leaking tank. AIC has also prepared codes of practice for the storage of liquid fertiliser.
