George Washington Carver was a brilliant scientist who worked primarily with agricultural tools and techniques, although he did use some basic laboratory equipment. Here's a breakdown:

Agricultural Tools and Techniques:

* Farming equipment: Carver was a farmer at heart, so he relied on tools like plows, hoes, and other implements used for planting, cultivating, and harvesting crops.

* Crop rotation: Carver was a pioneer in advocating for crop rotation, a technique that involves rotating different crops in a field to prevent soil depletion and pests.

* Soil analysis: He understood the importance of soil health and likely used simple methods to analyze soil composition, including observing soil texture and color.

* Plant breeding: Carver conducted extensive research on plant breeding, using selective breeding methods to develop new crop varieties.

* Field trials: He conducted field trials to test the effectiveness of his agricultural techniques and the performance of new crop varieties.

Basic Laboratory Equipment:

* Microscopes: Carver used microscopes to examine plant tissues and identify pests and diseases.

* Chemicals and glassware: He likely used basic chemicals and glassware for conducting chemical analyses and experiments.

* Simple analytical tools: Carver may have used some basic analytical tools to measure things like pH, moisture content, and nutrient levels in soil and plants.

It's important to note that Carver's work was primarily focused on practical applications and agricultural improvement. He wasn't necessarily using cutting-edge laboratory technology, but his innovative approach and knowledge of the natural world made him a highly effective and respected scientist.
