Tonya was amused when she heard the travelers behind her arguing about whether the purple flower was lavender or sage, and simply turned around and told them the correct answer:

"It's not lavender or sage, it's actually a pasture grass grown in the commune, which the locals call 'alfalfa.'"

"Huh? It turns out that grass can also produce such beautiful flowers. Someone sighed in surprise.

"Usually they are harvested and stored before flowering, but this year there are probably more important crops that have not yet been harvested, and the harvest of these grasses has to be postponed, and in any case, they must be harvested and processed before winter as winter fodder for livestock." Tonya added.

"It's really strange, there are weeds for livestock to eat, and it's a waste to grow pasture instead of growing food in such a good field." The "wanderer" brother who sat next to Roland shook his head repeatedly, unable to understand the local village's cultivation method of indiscriminate cultivation.

"I guess people do this for a reason, Tonya, isn't it?" Roland asked the professionals to interpret it.

Miss Druid nodded: "The plot of wheat cannot be cultivated year after year, otherwise the fertility of the soil will be exhausted in a few years, and the crop yield will not be as good as before, so the field after plowing will either rest and recuperate, or rotate pasture grass - pasture grass can not only provide nutritious fodder for livestock, but more importantly, the root system of this plant can solidify the soil and restore the fertility of the farmland." ”

The passengers around listened to Tonya's professional interpretation, and they all showed a look of sudden understanding. These people are either adventurers who hunt monsters everywhere or merchants who do small business and don't know much about the tricks of farming.

"How do you store the grass for the winter?" Someone asked Miss Druid, "Is it dried into hay after harvesting?" ”

"Drying and storing hay is indeed a common traditional practice in the Far East, but the grass loses most of its nutrients and moisture during the drying process, and the livestock does not taste good to chew and is not conducive to digestion and absorption. Tonya replied unhurriedly.

"What do you mean by 'silage'?" Lyudmila asked curiously.

"To put it simply, it is to harvest pasture or other forage crops before winter, cut it into about an inch long with a guillotine, and then dig a cellar to bury the chopped grass into the compact, cover it with a thick layer of straw, and finally cover the soil to compact, so that the grass in the cellar is isolated from the air, so that the stored grass is buried in the cellar for two or three years and will not rot, open the cellar to see that it is still verdant color, exudes a sweet and sour fragrance, and the livestock not only love to eat but also very nutritious." Tonya patiently explained.

Roland listened to Tonya talk about how to make silage, and the corners of his lips couldn't help but rise slightly. The druids may not know much about chemistry, but this does not prevent them from discovering almost identical agricultural techniques to the earth, such as silage.

Tonya explains to Lyudmila how the grass heats up spontaneously in an air-barred cellar and slowly ferments under the influence of a tiny organism to produce a yogurt-like aroma...... To Roland, in addition to the difference in the understanding and naming of the microorganism "lactic acid bacteria", how different is the research work of Tonya's druid community from that of the agronomists on Earth?

The natural environment and agricultural production methods similar to the earth determine that the two will inevitably have some different experiences in the field of agricultural technology, but after all, Vares is a world with magic and supernatural powers, so the agricultural technology under the leadership of the druids and the biological science on the earth will inevitably have a time to diverge, take silage technology as an example, because the grass itself contains very few lactic acid bacteria, but there are many other harmful bacteria, natural fermentation is very difficult, Insufficient fermentation will cause the grass to rot and deteriorate due to harmful bacteria during storage. On Earth, scientists have solved this problem by adding artificially produced lactic acid bacteria to the storage process to promote forage fermentation, while in Vares, where technology is not yet developed, the druids have taken another approach to solve this problem.

"Valentina-sensei has invented a 1-ring magic technique that allows you to ensure that the silage in the cellar is perfectly fermented by performing this 'Valentina Fermentation Technique' on the cellar while storing the grass, and at the same time, the harmful microscopic creatures that cause the feed to rot will be killed by the spell." Speaking of the teacher's great contribution to agriculture and animal husbandry in the Far East, Tonya exuded reverence from the bottom of her heart.

As soon as the train passed through the sea of alfalfa flowers, there was a wider sea of green ahead, and the tall plants gathered into thousands of blue waves, which were hidden in the golden color when rippling in the wind, and only on closer inspection could it be discerned that it was a mature corn cob, with the leaves breaking to reveal full particles and tassel-like tassels.

"This corn is also a crop in the valley village?" Lyudmila looked at Roland with a little surprise, "When we passed through the valley village three years ago, there didn't seem to be any corn growing ...... there."

"In fact, in the past, there was a small amount of planting, but the proportion of crops was very small, and the yield was not high, we were just passing by in a hurry, and we didn't pay attention, this year we planted a new variety of corn introduced from the Wilnoa region of the New World, which is more resistant to cold than the traditional varieties, and the yield is much higher, Ms. Valentina and I have selected a few farms to plant new varieties of corn on a large scale, and Valley Village is one of the pilots." Roland looked out the window at the farmland, chatting and observing the growth of corn, the ripe corn cob seemed to be showing off his good figure, most of them broke through the light green gauze skirt to expose the golden and full carcass.

"Wilnoa's Corn Seeds...... I think I've heard you talk about it. The female ranger patted her forehead, "That's right! When we first traveled to Baiou Harbor, you asked Lyubov Yangbo how to get corn seeds from the New World, could it be the corn we see now? ”

Roland smiled and nodded: "You guessed it, when I went to Baiou Port to visit, one of the important missions was entrusted by Ms. Valentina to ask Lyubov to help introduce new varieties of corn from the New World. ”
