Why Agriculture Fertilizer is Necessary
Agriculture fertilizer plays a vital role in modern farming practices. As the global population continues to grow, the demand for food production increases, making it essential to maximize crop yields. Fertilizers such as manure provide essential nutrients that plants need for optimal growth and development, resulting in higher crop yields and improved food quality. Healthy Farms explores the importance of agriculture fertilizer and how all-natural fertilizers like manure are highly beneficial options.

What Does Fertilizer Help?
Plants often require fertilizers to overcome nutrient deficiencies since they have limited options to acquire nutrients. For instance, nitrogen is a crucial nutrient that plants cannot absorb directly from the air and must obtain through the soil. When nitrogen levels are low in the soil, fertilizers like manure can provide an essential boost.
Potassium, on the other hand, is abundant in deep soil layers, usually around one kilometer beneath the surface, and beyond the reach of plant roots. Mining potassium deposits brings this nutrient to the soil surface and within the reach of plant roots.
Phosphorus is present in rocks, but it must be water-soluble for plants to access it. Correct usage of phosphorus fertilizers facilitates its absorption through the soil, leading to high productivity and faster growth of plants.
The Role of Fertilizers and All-Natural Options in Boosting Crop Yields
Plants require 17 essential nutrients to grow healthy, and different crops consume varying amounts of these nutrients. Farmers use varying fertilizers to address soil-specific nutrient deficiencies and meet crop requirements. Some use fertilizers that provide a combination of several nutrients, while others prefer all-natural fertilizers like manure and compost, which add nutrients and improve soil structure.
With the world’s growing population, meeting food demands is crucial, and since the 20th century, fertilizers have been widely used to boost crop yields. With an expected world population of over 9 billion people by the year , the need for carefully planned fertilization becomes increasingly vital to produce enough food to feed everyone. All-natural fertilizer is a great option for farmers as it utilizes the least amount of resources.
How All-Natural Agriculture Fertilizer Can Benefit Your Crops
All-natural fertilizers, like manure, offer a range of benefits to crops. Manure provides a concentrated and consistent supply of essential nutrients, promoting healthy plant growth and maximizing crop yields. It also improves soil structure, enhancing water retention and nutrient availability for plants. Manure promotes microbial activity in the soil, supporting beneficial soil organisms that aid in nutrient cycling and overall soil health. Finally, the use of manure as a natural fertilizer helps in recycling organic waste, reducing environmental pollution, and supporting sustainable agricultural practices.

Why do plants need fertilizers? | Yara International
When crops are harvested, important nutrients are removed from the soil, because they follow the crop and end up at the dinner table. If the soil is not replenished with nutrients through fertilizing, crop yields will deteriorate over time.
Careful analyzing and fertilizing of crops enables a chain that provides humans with nutritional food:
- The nutrients feed the soil
- The soil feeds the plants
- Plants feed animals and people
The three most common mineral fertilizers are those based on nitrogen, phosphorus and potassium.
The International Fertilizer Association (IFA) estimate that 85% of the soils globally are deficient in nitrogen(1). Seventy-three percent of the soils are deficient in phosphorus, whereas 55% lack potassium.
What is fertilizer used for?
Often, the plants have few possibilities to avoid nutrient deficiencies without the help of fertilizers.
Take nitrogen for example: Since plants are not capable of absorbing it from the air directly, the soil is their only means of acquiring this important nutrient. If the soil is low on nitrogen, fertilizers are needed to boost nutritional levels.

Large concentrations of potassium sources occur deep below the soil surface (often around one kilometer) and are far beyond the reach of plant roots. Mining of potassium brings this naturally occurring nutrient to the soil surface and within the grasp of plant roots.
Phosphorus exists in certain rocks, but for plants to access this nutrient, it needs to be water soluble. The correct use of phosphorus fertilizers helps plants absorb it through the soil and ensures a high production and rapid growth.
What is the difference between mineral fertilizers and organic fertilizers?
In nature there are 17 nutrients necessary for plants to thrive. What kind of fertilizer you need, depends on what crop you grow and the nutrient deficits in each specific soil. Different crops remove different amounts of nutrients from the soil.
Many farmers use NPK compound fertilizers that provide a combination of several nutrients at the same time.
Organic fertilizers such as animal waste and compost have been used for centuries and are a valuable source of nutrients and organic matter, which enhances soil structure.
But since the 20th century, mineral fertilizers have been required to meet the increasing food requirements of a growing world population. The amounts of nutrients in organic fertilizers vary and are much less concentrated than those in mineral fertilizers.
Mineral fertilizers reduce the amount needed and the number of vehicles to transport the fertilizing products.
By , the global population is estimated to reach 9.8 billion, according to the United Nations(2). Increasing crop yields is essential if we are going to be able to produce enough food for everyone.
This increase is not possible without carefully planned fertilizing.
What are the benefits of fertilizers?
Knowing the exact amounts of nutrients in the mineral fertilizer also makes it easier to plan the farming process. Fertilizers containing major, secondary and micronutrients are now more widely available to farmers.
Mineral fertilizers mostly come in a convenient solid granular form, which makes them well suited to transport and application by the farmer. Plants that grow in nutritionally deficient and unfertilized soil will often be smaller and grow slower than plants from healthy soil.
Why are nutrients important to humans?
When we eat wheat, apples, potatoes or other plants, the nutrients from the fertilized soil is transferred to our bodies. The same happens if we eat animals who have eaten plants with the same nutrients.
For example, milk is a good supply of calcium, which prevents us from developing weak and brittle bones.
But the milk will not contain as much calcium if the cows do not graze on fields with enough of this nutrient in the soil.
Growing food in soil with a good balance of nutrients is therefore key to preventing malnourishment. It also prevents illnesses related to deficiencies in populations across the world.
One example is Finland, where the government has mandated the addition of selenium to all multi-nutrient fertilizers since . In this way, they have managed to combat heart disease in the population with great success.
