Important Questions : Manures, Fertilizers and Soil Fertility Management

Important Questions 

1. **Define bulky and concentrated manure. How do they differ in terms of nutrient content and application methods?**

   - **Bulky manure** refers to organic materials such as animal dung, crop residues, and compost that are relatively low in nutrient concentration but high in volume. It typically requires large quantities for effective application. In contrast, **concentrated manure** is processed or treated organic material with a higher nutrient concentration per unit volume, often obtained through methods like composting or anaerobic digestion. Concentrated manure requires smaller quantities for application due to its higher nutrient content.

2. **What are the advantages of using bulky manure in agriculture? Provide examples of bulky manure sources.**

   - Bulky manure offers several advantages, including improving soil structure, enhancing water retention, and providing a slow-release source of nutrients. Examples of bulky manure sources include animal dung (such as cow, horse, or poultry manure), crop residues (like straw or hay), and green manure crops (such as legumes).

3. **Explain the process of preparing concentrated manure. How does it contribute to enhancing soil fertility?**

   - Concentrated manure is typically prepared through processes such as composting or anaerobic digestion. Composting involves the decomposition of organic materials under controlled conditions, resulting in a nutrient-rich product. Anaerobic digestion breaks down organic matter in the absence of oxygen, producing biogas and a nutrient-rich digestate. These processes help break down complex organic compounds into simpler forms that are more readily available to plants, thereby enhancing soil fertility.

4. **Compare and contrast the effects of bulky and concentrated manure on soil structure and nutrient availability.**

   - Bulky manure improves soil structure by adding organic matter and enhancing soil aggregation, which promotes aeration and water infiltration. However, it releases nutrients slowly over time. In contrast, concentrated manure provides nutrients in a more readily available form, leading to faster nutrient uptake by plants. However, concentrated manure may have less impact on soil structure compared to bulky manure.

5. **Discuss the role of bulky and concentrated manure in promoting sustainable agriculture practices.**

   - Both bulky and concentrated manure play key roles in sustainable agriculture by recycling organic waste, improving soil health, and reducing dependence on synthetic fertilizers. Bulky manure helps build soil organic matter and enhances long-term soil fertility, while concentrated manure provides a more concentrated nutrient source, reducing the need for chemical fertilizers and minimizing nutrient runoff.

6. **How does the application of bulky and concentrated manure impact crop yield and quality? Provide empirical evidence or case studies to support your answer.**

   - Research studies have shown that the application of bulky manure can significantly increase crop yields and improve crop quality over time by enhancing soil fertility and nutrient availability. Similarly, the use of concentrated manure has been linked to improved crop growth and yield due to its high nutrient content. For example, a study conducted by [research institution or organization] demonstrated that the application of composted manure increased yields by [percentage] compared to synthetic fertilizer alone.

7. **What factors should farmers consider when selecting between bulky and concentrated manure for their agricultural practices?**

   - Farmers should consider factors such as nutrient content, application cost, availability, soil type, crop requirements, and environmental considerations when choosing between bulky and concentrated manure. Bulky manure may be preferred for long-term soil health and organic matter addition, while concentrated manure may be more suitable for addressing specific nutrient deficiencies or optimizing nutrient management in intensive cropping systems.

Important Terminology : Rainfed Agriculture Highlights

Humidity: In rainfed agriculture, humidity refers to the amount of moisture present in the air. High humidity levels can affect the growth of crops, as excessive moisture in the air can lead to diseases and fungal infections in the plants.

Fog: Fog can be a common occurrence in rainfed agriculture, especially in regions with high humidity. It can reduce the amount of sunlight reaching the crops and increase moisture levels, potentially leading to mold and mildew on the plants.

Frost: Frost occurs when temperatures drop low enough to freeze the moisture on plants, potentially damaging or killing them. In rainfed agriculture, frost can be particularly damaging to crops, especially if they are not cold-tolerant.

Dew: Dew is the moisture that forms on plants and other surfaces during the night as a result of condensation. In rainfed agriculture, dew can provide some moisture to the crops, especially in areas where rainfall is scarce.

Wind: Wind can have both positive and negative effects on rainfed agriculture. Strong winds can cause soil erosion and damage to crops, while gentle breezes can help in pollination and reduce the occurrence of fungal diseases by promoting air circulation.

Important History Highlights :

The First Famine Commission in 1880, was tasked with finding ways to deal with droughts that had been occurring since 1860. The commission recommended the establishment of protective irrigation projects.

First systematic scientific approach to tackle the problems of dry farming areas was initiated by Tamhane in 1923 on a small plot at Manjri Farm near Pune

The ICAR selected 25 dryland agricultural centers all over the country on the basis of the moisture deficit, soil type, and rainfall characteristics

 The Green Revolution in the mid-1960s, there was a wide disparity in productivity between irrigated and rainfed agriculture. This led to a focus on improving the agricultural development of dryland regions during the Fourth Five-Year Plan (1969-1974). 

 In response, the Indian government launched the All India Coordinated Research Project for Dryland Agriculture (AICRPDA) in collaboration with the Canadian International Development Agency (CIDA) in 1970.

Ways to write CSS in HTML

There are three ways to CSS in html file .

·        Inline css

·        Internal css

·        External css

Priority Order

            Inline > Internal > External

 

Inline CSS

è Before CSS we use inline to apply style

è Not an efficient way to write

è Self contained

è Uniquely applied to each content element

Example –

            <h3 style=” color : red”> Have a great day </h3>

            <p style –“color; purple”> I make this </p>

 

Internal CSS

·        With the help of style tag we apply styles with the HTML file .

·        Redundancy is removed

·        But idea of speparation concern still lost

·        Uniquely applied on single document

·        Example –

<style>

            H1 {

            Color : red;

            }

</style>

<h3> Have a good sweet night </h3>

External CSS

·        With the help of  <link> tag in head we apply styles

·        Reference is added

·        File saved with css extension

·        Redundancy is removed

·        Idea of separation is maintained

·        Uniquely applied in each contents

Example –

            <link rel=”stylesheet” type=”text/css” href=””>

            H1 {

                        Color : red;                                                                   //.cssfile

            }

 

CSS Selectors

·        Selectors are used target and apply CSS

·        Three simple selectors

o   Element Selectors

o   Id selectors

o   Class selectors

·        Priority selectors

Id> Class> Element

Id Selectors

·        Id attributes is used to select HTML element

·        Used to target specific or unique element

·        How we do it ?

#unique

            {

            Color: red;

            }

            <H1 ID=” unique”> Hello world </p>

Firstly we select the id and then change the color property , text color to red.

And then written text in the content tag will change the color to red.

 

Class Selectors

·        Class attribute is used to select HTML element

·        Used to target specific class of element

·        How we do –

.group {

Color: red;

}

<h1 class =” group”> Heloo litty </h1>

We select the class and then changed the color property , text color to red.

Then written text in this tag content will have the text color as  red.
