Question

Describe about 4r principal

Answer 1

Hey mate here is your answer:-)

The 4R nutrient stewardship principles are the same globally, but how they are used locally varies depending on field and site specific characteristics such as soil, cropping system, management techniques and climate. The scientific principles of the 4R framework include:

RIGHT SOURCE – Ensure a balanced supply of essential nutrients, considering both naturally available sources and the characteristics of specific products, in plant available forms.

RIGHT RATE – Assess and make decisions based on soil nutrient supply and plant demand.

RIGHT TIME – Assess and make decisions based on the dynamics of crop uptake, soil supply, nutrient loss risks, and field operation logistics.

RIGHT PLACE – Address root-soil dynamics and nutrient movement, and manage spatial variability within the field to meet site-specific crop needs and limit potential losses from the field.

Answer 2

REDUCE:We should reduce the use of materials that are harmful to us.Like:We should use paper bags instead of polethene bags.

REUSE:We should reuse things like plastic bags can be used to make decorative things.

RECYCLE:We should give waste things (which cannot be decomposed) for recycling.like plastic materials.

RECOVER: If there is still waste left over after we have reduced, reused and recycled as much as we can, we can use it to make energy at our energy-from-waste (EfW) facility. This process is known as Recovery.
