Better quality plants attract insects so pesticides may be needed. Excess nitrogen from fertilisers gets into water supplies, causing fish to die. damage their health by applying fertilisers, pesticides and herbicides incorrectly. Artificial fertilisers, applied without organic additions, do not improve soil structure.

Other advantages to multiple cropping include an improved balance of soil nutrients and the suppression of weeds, diseases and pests. It also leads to an increase in overall productivity. One key disadvantage to mixed cropping is the limitations it places on capacity.

Chemical fertilisers pollute the groundwater, rivers and lakes. (ii) The continuous use of chemical fertilisers has led to degradation of soil health. Environmental resources like soil fertility and groundwater are built up over many years. Once destroyed it is very difficult to restore them.

The benefit of using coffee grounds as a fertilizer is that it adds organic material to the soil, which improves drainage, water retention and aeration in the soil. The used coffee grounds will also help microorganisms beneficial to plant growth thrive as well as attract earthworms.

That's where fertilizer comes in. Nitrogen, phosphorus and potassium, or NPK, are the “Big 3” primary nutrients in commercial fertilizers. Each of these fundamental nutrients plays a key role in plant nutrition.

As the soil absorbs manure, nutrients are released. ... Adding manure to compacted soil helps loosen the soil. Manure produces increased soil carbon, which is an important source of energy that makes nutrients available to plants. Other benefits of manure include reduced runoff and leaching of nitrates in the soil.

When to Fertilize Late summer and early fall are the best times of year to fertilize your garden and lawn. According to the University of Minnesota, early spring applications of fertilizer can make your lawn look nice from the surge of top growth, but it ultimately depletes the plants' energy reserves.

The simplest way to distinguish between compost and fertilizer is to remember this: Compost feeds the soil and fertilizer feeds the plants. ... Compost and organic fertilizers can work together. The organic matter in compost sponges up the fertilizer nutrients until they are needed by plants.

disadvantage:A high possibility that pollen grains won't reach and fertilize or pollinate the plant. advantage:the seeds can travel a long on the wind,the plants migrate or move to other areas, and are not all bunched in one place.

Organic materials and fertilizers improve the soil texture, allowing it to hold water longer, and increase the bacterial and fungal activity in the soil. So, they not only assist your plants, they help the soil. Synthetic fertilizers, on the other hand, deplete the soil of its nutrients, making it unproductive.

Sandy Soil: Advantages and Disadvantages. Sandy soils are light and gritty to the touch. Because sandy soils have large particles, they dry out quickly, are often low in nutrients and acidic. Both water and fertilizer have a tendency to leach out of the soil - escaping to waterways before the plant can utilize them.

Fertilizers are not plant food. Plant nutrition refers to the plant needs and uses of the basic chemical elements. ... Fertilizers are materials containing plant elements or nutrients. Generally, they are added to water or soil, but some can be added to water and sprayed on leaves.
