It is an approach of studying soil in which it focuses to its origin and classification as its occurs in the environment. This is knows as _________.

Mang Kanor is a farmer, he produces many types of vegetable crops in his garden. What type of approach did Mang Kanor belongs?

There are four process of soil formation. Which of the following that this statement belongs "movement of soil materials from one place to another mainly due to water".

There are four major components of soil. Evaluate which of the following components comprises least amount of material incorporated into the soil?

If the amount of mineral matter is 43% and the water is 7%, how much the availability of organic matter and the soil Air present in the soil sample?

Compared to the primary minerals, the secondary minerals are those minerals that form from _________.

There are three classes of rocks, identify which of the following did magma belongs?

It is a formation of rocks through the process of heat and pressure or chemical action, generally harder than the original rocks.

There are two types of igneous rocks (intrusive and extrusive), assess the two types of igneous rocks.

Sedimentary rocks are formed from the weathering of rocks exposed at the earth surface. The process involved the following EXCEPT.

Weathering is the process of physical and chemical alteration of rocks or minerals at or near the earth surface. Which of the following did crystallization of salts belong?

Weathering is the process of physical and chemical alteration of rocks and minerals at or near the earth surface. Which of the following did water molecules incorporate into the structure of minerals belongs?

Physical weathering is the alteration of the physical properties of the materials without changing its chemical composition. All of this are the processes of physical weathering EXCEPT.

There are processes in chemical weathering, distinguish which process did this statement belongs "incorporation of water molecules into the structure of minerals".

Primary mineral is formed from the crystallization of magma. Which of the following is Not a type of primary minerals?

This is termed used for a true soil or A and B horizons.

This is a termed used for A, B and C horizons.

Horizon O is an organic horizon that comprises three sub-horizons. Which of the following did sapric (highly decomposed organic horizon) belongs?

This is the unconsolidated material underlying the solum, relatively unaffected by the soil genetic processes.

Soil profile is a vertical section of the soil showing its horizons. Arrange the following according to the correct sequence of a Master horizons?

Horizon O had three sub-horizons namely: Oi, Oe and Oa. Choose which of the following is the correct paired of sample according to the decomposition.

Choose which of the following master horizon did topmost mineral matter occurs?

In a soil profile with O, A, E and B horizons, evaluate which of the following is the least amount of clay in the horizon.

Soil formation is the process by which soil is formed as a result of interactions over time between parent materials, climate, topography and organisms. Choose which of the following is NOT a function of organism in soil formation?

Topography is the arrangement of the natural and artificial physical features of an area. The following are the effects of topography in soil formation EXCEPT.

There are terms called for a major factor in soil formation, choose the correct term for each factor of soil formation.

The five soil forming factors

________to determine the soil characteristics.

It is a type of soil physical properties that you may identify according to its soil particle groupings.

Sand, silt and clay are the components of soil texture and classify as __________.

It is considered as the basic structural unit of soil.

Sandy soil have a high water holding capacity, more micro-pores and very difficult to till.

A proportion of 30% sand, 35% silt and 35% clay. Identify what type of soil is this?

At the same level of organic matter, evaluate which are the highest water holding capacity?

A type of soil structure that is cube-like and common in B horizon especially in the humid regions.

Bulk density is a measure of compaction or looseness of the soil, therefore, the higher the bulk density is an indication of higher porosity.

Bulk density is an indication of soil porosity and soil texture.

A soil with high in particle density is also known as more porous.

A soil from a field had mass of 47.80 grams and a volume of 32.50 cm3. The oven dry mass of a soil was 35.50 grams. Calculate the bulk density of a soil.

Based on the problem above, calculate the pore space of a soil if the bulk density is 1.09g/cm3 and a particle density was 2.65g/cm3.

A soil with bulk density of 1.30g/cm3 and a particle density of 2.60g/cm3 will have a porosity of ________.

Calculate the gravimetric moisture content of the soil sample if it's fresh weight (FW) is 25 grams and its oven dried weight (ODW) is 20 grams.

Calculate the percent of volumetric moisture content if the gravimetric is 25%, bulk density of 1.20g/cm3 and water density of 1.00g/cm3.

If the amount of mineral matter is 43% and the water is 7%, how much the availability of the organic matter and the soil Air present in the soil sample?

Two types of water holding in the soil, assess which of this statement belongs "after the rain, water from raindrops attracts to the available water present in the soil".

After heavy rain, the farm area of Mang Kanor is fully filled up with water. What type of soil moisture coefficient happened in the field?

After heavy rain, the percent water remaining in soil 2 to 3 days after filled up and after free drainage has practically ceased.

Summer season when mang Kanor planted his cucumber plant. a few weeks after, his plants begin to wilt and later the plants die. What type of soil moisture coefficients happened in the field?

The color of the soil indicates some chemical conditions.

The best way to increase water holding capacity and nutrient supplying capacity of a coarse-textured soils is to_________.
