Dear students, in this 2nd and highly crucial eco-friendly chapter of Class 12 Agriculture strictly known as 'Organic Farming', we will deeply study 1 highly sustainable and scientific alternative to modern chemical farming from 1 strictly logical perspective. In massive recent times, the blind and massive excessive use of chemical fertilizers and toxic pesticides has 100 percent severely damaged our massive soil, pure water resources, and human health. Therefore, massive organic farming is 100 percent the strict need of the hour. It is 1 highly advanced scientific method of agriculture where harmful chemicals are strictly avoided, and 100 percent natural and biological resources are utilized. From the strict perspective of the upcoming massive board exams and specifically the highly competitive Rajasthan Joint Entrance Test (JET Exam), ICAR, and CUET, this chapter is 100 percent highly scoring and 1 absolute massive milestone for your excellent academic success.
In this highly exciting learning journey, we will 1st logically analyze the strict massive principles of Organic Farming. We will scientifically understand how massive crop rotation, mixed farming, and the scientific use of massive organic manures 100 percent naturally restore massive soil fertility without harming the delicate environment. After this, we will systematically study the massive 'Organic Manures'. The strict scientific preparation and massive benefits of Farm Yard Manure (FYM), massive Compost, and specifically 'Vermicompost' (which is 100 percent magically prepared strictly using earthworms) are 1 highly crucial topic. In the massive JET Exam, objective questions strictly based on the specific massive earthworm species used for vermicomposting (like Eisenia fetida) are 100 percent directly asked.
Moving 1 little further in the highly detailed chapter, we will logically evaluate the brilliant scientific concept of 'Green Manure'. Growing leguminous massive crops like Sunhemp or Dhaincha and 100 percent ploughing them directly into the massive soil in their strict green stage magically provides massive natural nitrogen and rich organic matter. Alongside this, we will deeply study massive 'Bio-Fertilizers'. Microorganisms like massive Rhizobium, Azotobacter, and Azospirillum strictly fix massive atmospheric nitrogen and 100 percent efficiently make it highly available to the massive plant roots.
Finally, we will completely study the brilliant scientific methods of 'Biological Control' of massive pests and diseases. Instead of highly toxic chemicals, friendly massive organisms like Trichoderma and Chrysoperla are 100 percent utilized to strictly destroy massive harmful agricultural pests. To perfectly ensure your excellent and 100 percent strong board and JET preparation, we have meticulously prepared highly accurate objective questions from all these complex topics. By continuously practicing, you will surely learn critical time management and increase your speed of solving complex questions.
Feature: This is 1 3-Level based unique quiz. To unlock the next level (Level 2 and 3), students must strictly score at least 70% in the current level, making their board and JET exam preparation 100% strong.
