Chapter 35, Problem 12TYK
Summary Introduction
To review:
The need for reconditioning the soil for a plot where annual plants are grown and the strategies that can help in limiting the need for reconditioning.
Introduction:
Annual plants are the plants that complete their life cycle in a year. This means that from germination to development of new seeds on the plant takes a year. After completion of the growth year, the plant dies. Continuous farming on land results in deteriorating the soil quality.

Discuss the following prompt:
In this experiment, we are looking to see how much different types of soil will affect the time it takes for pinto Bean seedlings to germinate out of the ground. The scientific name of a pinto bean is Phaseolus vulgaris. Pinto beans are kind of beans people usually eating, and people commonly use pinto beans in many dishes, such as rice and pasta. Planting pinto beans need many necessary factors, however, I think the type of soil is the most important one to grow it faster. Pinto beans are kind of plants can grow in dark and dry area, so even in dark (less light), they can grow as well. The goal is to determine that soils have different characteristics that can help or hurt plant growth.
In order to discover the effects soils have on plant growth, three different soil samples will be used in a controlled study. The samples will vary in consistency, texture, color, location, moisture, and contact with human life to ensure that the samples are…
Fertile soil is one of the keys to good yield.
