Organic material provides nitrogen for plants. which soil component contributes the most nitrogen to plants?

The answer is Humus or Topsoil. Humus is made up of decayed organic material, forming a fertile and nutrient-filled soil.

The Humus or the topsoil present in the soil is the biggest source of nitrogen for the plants as it is formed from organic material of leaves and animals.

Explanation:

The soil is made up of several components that are present in different proportions. The quality of the soil depends on the amount of a particular substance present in the soil.

The fertility of soil is determined by the amount of minerals present in the soil. the organic materials present in the soil play the important role in meeting different requirements of the plants as they grow.

The nitrogen is one of the most important requirement of the plant as they grow. The requirement of the nitrogen for a plant is fulfilled by the organic compounds present in the upper layer of the soil.

This upper layer of the soil is rich in organic components and it is called as the humus. The other parts of the soil like clay, silt etc. are not rich in the organic components. So, they cannot supply sufficient nitrogen to the plants.

Thus, the Humus or the topsoil present in the soil is the biggest source of nitrogen for the plants as it is formed from organic material of leaves and animals.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
