Organic fertilizer, chemical fertilizer, and biofertilizer are the three types of fertilizers most commonly used in modern agricultural production. High yields and superior quality in agriculture depend on proper fertilization, which requires a thorough understanding of each fertilizer’s functions and differences. ● Organic fertilizer is a carbon‑containing material primarily derived from plant and/or animal residues, applied to the soil mainly to supply nutrients to plants. It is produced by processing biological materials, animal and plant waste, and plant remains, thereby eliminating harmful substances and enriching it with numerous beneficial components, including various organic acids, peptides, and an abundance of essential nutrients such as nitrogen, phosphorus, and potassium.

Organic fertilizer, chemical fertilizer, Biofertilizer These three types of fertilizers are among the most widely used in modern agricultural production. Achieving high yields and superior quality in agriculture hinges on proper fertilization, which requires a thorough understanding of each fertilizer’s functions and distinctions.

● Organic fertilizer

A carbon‑containing material whose primary raw materials are plant and/or animal residues, applied to the soil primarily to supply plant nutrients. It is produced by processing biological matter, animal and plant waste, and plant residues, thereby eliminating toxic and harmful substances while enriching it with a wealth of beneficial compounds, including various organic acids, peptides, and an abundance of essential nutrients such as nitrogen, phosphorus, and potassium. Not only does it provide comprehensive nutrition for crops, but it also delivers long‑lasting fertilizing effects, increases and replenishes soil organic matter, promotes microbial proliferation, and enhances the soil’s physical and chemical properties as well as its biological activity, making it a key nutrient source for the production of green foods.

● Inorganic fertilizer

Inorganic fertilizers, also known as mineral fertilizers or chemical fertilizers, are produced through chemical synthesis. They include nitrogen, phosphorus, potassium, and compound fertilizers. Characterized by their simple composition, high content of available nutrients, rapid solubility in water, quick decomposition, and easy absorption by plant roots, they are commonly referred to as “fast-acting fertilizers.”

● Bio-organic fertilizer

Bio‑fertilizers are products in which the life activities of microorganisms confer specific fertilizing effects on crops, and they constitute one category of fertilizers used in agricultural production. The efficacy of microbial fertilizers hinges on the diversity of beneficial microorganisms and the vigor of their metabolic activity, unlike conventional fertilizers that rely primarily on the form and quantity of major nutrients such as nitrogen, phosphorus, and potassium. As live‑culture products, the performance of microbial fertilizers is closely linked to the number and viability of the active microorganisms, as well as to environmental factors—including temperature, moisture, soil pH, nutrient availability, and the suppressive effects of indigenous soil microbes—each of which can exert a measurable influence.

Biofertilizer, organic fertilizer, chemical fertilizer

A balanced combination of biofertilizers, organic fertilizers, and chemical fertilizers.

First, pay attention to the timing of application.

Organic fertilizers take longer to show effects, so they should be applied well in advance—typically as a single basal application before sowing or transplanting. It is best to compost them thoroughly prior to use; applying them as a topdressing later in the growing season will yield less pronounced results than using them as a base fertilizer.

Chemical fertilizers deliver rapid results; when used as a base fertilizer, apply them about one week in advance, and for topdressing, apply them before the crop’s critical nutrient‑demand period or peak nutrient‑uptake phase to meet its nutritional needs.

Bio‑fertilizers containing beneficial microorganisms can exert their antagonistic effects only after they have multiplied extensively in the soil; therefore, they should be applied well in advance of transplanting to allow sufficient time for their proliferation and growth. They may be incorporated into the soil along with organic fertilizers, or applied in planting holes prior to or at the time of transplanting.

Secondly, pay attention to the application method.

Organic fertilizers primarily improve soil quality while supplying nutrients. They are typically applied as base fertilizer, so they should be incorporated through deep tillage to ensure thorough mixing with the soil, thereby achieving the goal of soil improvement. When soil problems are severe, they can be used in conjunction with acid–alkali‑neutralizing microbial agents to further enhance the soil environment, balance nutrient levels, and promote the development of a well‑structured soil aggregate.

In base fertilization, since organic fertilizers are primarily rich in nitrogen, the amount of nitrogen fertilizer applied alongside them can be reduced: 30% may be used as a base application, with the remaining 70% applied as a topdressing. Phosphate and potash fertilizers can be applied once as a base dressing; because phosphate fertilizer has poor mobility, late‑season topdressing is of limited effectiveness, so it should be incorporated into the soil as a base application.

For topdressing, it is best to use fully water-soluble, fast-acting fertilizers, such as Phosphorus-Potassium Source Depot; these fertilizers are rapidly absorbed by vegetables after decomposition and have minimal impact on the soil. Bio-organic fertilizer Due to its low application rate, it can be applied in concentrated doses directly into the planting hole or incorporated as a base fertilizer along with organic matter. In the later growth stages, the same bio‑fertilizer can be top‑dressed multiple times to bolster the microbial population, thereby enhancing its ability to solubilize phosphorus and potassium and improving disease‑control efficacy.

Thirdly, pay attention to the application rate.

The fertilizer requirements vary across different crops and growth stages; applications should neither exceed nor fall short of the recommended amounts. Fertilization should be tailored to each crop’s specific nutrient‑requirement ratios, while also taking into account the existing levels of nutrients in the soil and adopting a holistic approach.

CCTV.com reports: Against the backdrop of comprehensively advancing rural revitalization and accelerating agricultural modernization, agricultural scientific and technological innovation has become a key driving force for green agriculture. Leveraging the research platforms of Shandong Agricultural University, Shandong Nongda Fertilizer Technology Co., Ltd. has successfully developed a new functional foliar fertilizer called “Nongda Leaf Power.” Field trial data confirm that this product significantly enhances crop photosynthetic efficiency and improves fruit quality, offering a fresh solution for boosting agricultural productivity and quality.
