Organic hemp fertilisation: benefits and dangers of excessive use

Did you know that proper fertilization is a key factor for successful cannabiscultivation? In today's article we will focus on organic fertilisation and its importance for healthy plant growth and development. We will explore natural nutrient supply, the benefits of organic farming and how to achieve optimal results.

The benefits of organic fertilisation

  • Natural and balanced nutrient supply: natural nutrient supply is the process by which plants obtain the nutrients they need from soil, water and air. A balanced supply means that plants receive the optimum amount of all the nutrients they need for healthy growth and development. In this way, plants are able to function properly, develop and resist stress and disease.

  • Supporting the soil microflora and improving soil structure: the soil microflora includes micro-organisms such as bacteria and fungi that live in the soil and play an important role in the decomposition of organic material and the exchange of nutrients between plants and soil. Organic fertilisation promotes the development of these micro-organisms and thus creates a healthy soil microflora. Improved soil structure results in better water and air retention, which allows plant roots to penetrate the soil and take up nutrients better.

  • Reducing negative environmental and health impacts: The use of organic fertilisers helps to reduce negative environmental impacts. Organic fertilisers are made from natural materials and their use does not cause unnecessary chemical pollution of soil, water or air. This protects biodiversity and keeps the ecosystem in balance. At the same time, organic fertilisation reduces the risk of exposure to chemicals that can have a negative impact on human and animal health.

Types of organic fertiliser for cannabis

  • Compost: Compost is an organic material that is produced by the decomposition of organic residues such as crop residues and green waste. It is rich in nutrients and improves soil structure. Adding compost to the soil will increase its fertility and supply the plants with the necessary nutrients.

  • Guano: Guano is an organic fertiliser derived from dried excrement of seabirds or bats. It contains high amounts of nitrogen, phosphorus and potassium, which are very important nutrients for plant growth. Guano is also rich in trace elements, which are essential for plants.

  • Fish emulsion: Fish emulsion is a liquid organic fertiliser obtained from fish carcasses and waste. It contains high levels of nitrogen and trace elements. It is easily absorbed by plants and provides them with a rapid supply of nutrients.

  • Vermicompost: Vermicompost is compost that is produced by earthworms. Earthworms break down the organic material and improve its structure. Vermicompost is rich in nutrients, enzymes and micro-organisms that contribute to healthy plant growth.

It is important to choose an organic fertiliser that suits the needs of the cannabis plant and the growing conditions. When applying organic fertiliser, it is also important to follow the recommended dosage and application procedure to avoid over-fertilisation of the plants and negative impacts on the soil and the environment.

Dangers of excessive use of organic fertilisers

There are many benefits to using organic fertilisers when growing cannabis, but it is also important to be cautious and follow the recommended dosage. Excessive use of organic fertilisers can have negative effects on plants, soil and the environment.

  • Overfertilising plants: Adding too much organic fertiliser can lead to overfertilisation of plants. Excess nutrients, especially nitrogen, phosphorus and potassium, can cause root scorch, increased susceptibility to disease and negatively affect plant growth and development.

  • Pollution of water sources: excessive use of organic fertilisers can leach nutrients into water sources. This can cause eutrophication of aquatic ecosystems, where excessive nutrients in rivers, lakes or seas increase significantly. Eutrophication leads to excessive growth of algae and other plants in the aquatic environment, which has a negative impact on biodiversity and water quality.

  • Soil imbalance: Excessive use of organic fertilisers can cause imbalances in the soil. Excess nutrients can lead to soil acidification or pH changes, which can negatively affect soil micro-organisms and reduce their ability to break down organic matter.

Proper use of organic fertilisers

  • Dosage according to plant needs: It is important to follow the recommended dosage of organic fertilisers, which includes the correct amount of nutrients for the specific growth stages of the plant. Too little fertiliser can lead to nutrient deficiencies, while too much can cause over-fertilisation of the plants.

  • Application in accordance with soil conditions: Before applying organic fertilisers, it is advisable to carry out a soil analysis to provide information on soil pH and nutrient content. Based on this information , the soil pH can be adjusted and missing nutrients can be added.

  • Correct application timing: Organic fertilisers should be applied before planting or when preparing the soil for cannabis cultivation. It is also possible to apply fertilisers in the form of compost or organic mulches during the growth of the plants.

  • The advantage of organicfertilisers is their diversity. It is possible to combine different types of organic fertiliser such as compost, manure, guano or seaweed to ensure a balanced supply of nutrients to the plants.

  • Maintaining the soil microflora: Organic fertilisers have a positive effect on the soil microflora, which is important for the decomposition of organic matter and the supply of nutrients to plants. It is important to maintain soil micro-organisms by avoiding the use of chemical fertilisers and pesticides that could negatively affect the soil ecosystem.

  • Regular monitoring of plants: Regular monitoring of plant growth and response to fertiliser applications is important to optimise application rates and ensure proper nutrient supply to plants.

Following these recommendations for the correct use of organic fertilisers will contribute to healthy and sustainable cannabis cultivation and minimise negative environmental impacts. If you have any uncertainties or questions, it is advisable to consult with experts in cannabis cultivation or agronomy who can provide further specific advice and recommendations.
