Advantages and disadvantages of chemical fertilizers

Chemical fertilization uses products that help the plant with nutrients for easy and better growth, keeping the crop healthy for higher production and good quality.

These fertilizers are made with essential macronutrients for the soil, such as nitrogen, phosphorus and potassium, making them potent and powerful.

In addition to these macronutrients, they may contain ammonium sulfate, urea and anhydrous ammonia, among other compounds, depending on their structure and the crops and soils for which they are intended.

No soil is perfect for every plant. Therefore, fertilizers of all types provide additional nourishment in the soil, keeping plants healthy, vigorous and fruitful.

Whether with a special blend or a simple fertilizer, you can target the needs of a specific plant by giving it only the nutrients it needs.

Advantages and disadvantages of chemical fertilizers

Synthetic fertilizers allow plants to absorb nutrients faster than those obtained from unfertilized soil or natural fertilizers.

Dry forms of synthetic fertilizers usually cost less than organic fertilizers.

Some synthetic fertilizers have time-release characteristics .

Sometimes, when seaweed fertilizers are sprayed, new growth and stronger stems are produced within a few days.

Advantages of chemical fertilizers

The main positive effect that fertilization offers is the increase of crops, improving the plant and helping for a good development. They allow to increase production and keep the crops lush and nourished.

Fertilizers and fertilizers presented in the market may contain essential macronutrients such as: carbon (C), oxygen (O), hydrogen (H), nitrogen (N), phosphorus (P), sulfur (S), potassium (K), calcium (Ca) and magnesium (Mg), in addition to micronutrients needed in smaller quantities with respect to the previous ones such as: iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), nickel (Ni) and chlorine (Cl) and among other compounds that improve crop efficiency.

When buying fertilizers or fertilizers it is important to verify the components, effectiveness and quality according to the type of plant / soil to be applied, since the objective is to improve production by providing nutrients and maintaining the balance of the soil.

Disadvantages of chemical fertilizers

The use of chemical fertilizers can have disadvantages and negative effects. In order to have more sustainable practices, it is necessary to find balance points and complement them with organic fertilizers and compounds, as well as to constantly analyze soils and plants to make sure that the different values are the ideal ones and to detect negative reactions in time.

Some of the disadvantages of excessive and uncontrolled use include:

  • Soil degradation

Mismanagement of these products degrades the soil to the point of long-term infertility: this is due, among other things, to the fact that they can substantially increase acidity levels, generate macronutrient saturation or alter it to such an extent that the soil loses sensitivity and absorption capacity to different nutrients.

  • Groundwater contamination

These waters are a natural source of nutrients, minerals and vitality for crop plants: if they become polluted, not only can they represent losses in the immediate production cycle, but also compromise the future of agricultural activity in the area.

  • Salt burns

These burns are an alert of the deficient or exaggerated use of chemical fertilizers and evidence the dehydration of plant tissue, which hinders its correct development and even compromises productivity. Fertilizers with a high salt index (with compounds such as sodium nitrate) are the ones that require more attention and follow-up to avoid salt burns.

  • Exaggerated growth

Plant dimensions and sizes can exceed normal parameters due to excessive and unorganized application of chemical fertilizers. A size above normal rates represents excessive pressure on foliage and roots and also has an influence on soil degradation or deterioration, which compromises harvest and plant survival.

Chemical fertilizers are great allies of intensive agriculture, but they can also affect production cycles, soils and surfaces if they are administered and applied incorrectly.

Combining them with organic compounds, continuous monitoring and, in general, aiming for rationality are key aspects to increase productivity in a safe and sustainable way.
