Em relação à amostragem de solo e planta como ferramenta para posicionamento de corretivos e fertilizantes, analise as assertivas a seguir, assinalando V, se verdadeiras, ou F, se falsas.
( ) A amostragem de solo e planta pode ser realizada em qualquer época do ano.
( ) Em áreas de solos com sistema plantio direto, a amostragem de solo deve ser efetuada com trado de rosca ou holandês ou outro qualquer. Esses são os mais indicados, pois além de apresentar boa performance de coleta, também são de baixo custo de aquisição.
( ) Para áreas com sistema de preparo convencional de solo (aração e gradagem ou escarificação), a camada a ser amostrada é de 0 a 20 cm, enquanto para sistema plantio direto é de 0 a 10 cm, com monitoramento eventual da camada 10 a 20 cm.
( ) Para o plantio de espécies frutíferas e florestais, o solo deve ser amostrado na camada 0 a 40 cm de forma em caminhamento zigue-zague na gleba, antes de iniciar o cultivo.
( ) A concentração de nutrientes nas folhas é proporcional ao seu crescimento. Logo, não há uma necessidade de seleção de folhas jovens ou maduras para coleta, uma vez que há ferramentas para se corrigir essas diferenças.
A ordem correta de preenchimento dos parênteses, de cima para baixo, é:

As diferentes opções de moléculas químicas disponíveis no mercado têm e vêm permitindo o manejo de plantas daninhas, com relativo sucesso, nos últimos 30 anos. Relacione a Coluna 1 à Coluna 2 quanto ao tipo de herbicida e seu local, modo de ação ou sintomas.
Coluna 1
1. Inibidores de ACCase.
2. Inibidores e ALS.
3. Inibidores de EPSPS.
4. Auxinas sintéticas.
5. Inibidores do fotossistema 1.
Coluna 2
( ) São pertencentes ao grupo dos bipiridilos, sendo seu mecanismo de ação explicado em função de processos de produção de radicais livres convergindo, finalmente, para peroxidação das membranas celulares.
( ) Atuam na rota de síntese dos aminoácidos aromáticos fenilalanina, tirosina e triptofano. Uma vez nas plantas, esse herbicida é sintetizado no citoplasma e é transportado ao cloroplasto, em uma forma de “pré-enzima”.
( ) Atuam como reguladores de crescimento vegetal que interferem na elongação celular. Quando dentro da célula da planta, um os produtos é o acúmulo de cálcio no citoplasma, estimulando a produção de etileno e acidificação da parece celular.
( ) São posicionados para controle de gramíneas em pós-emergência, seletivamente para culturas dicotiledôneas em geral. Um dos principais sintomas é a desestruturação da região basal do “cartucho” das gramíneas.
( ) Tem como alguns dos representantes as imidazolinonas e sulfonilureias. Os principais usos são para controle de plantas daninhas dicotiledôneas, podendo também controlar algumas gramíneas. A planta cessa seu crescimento poucas horas após a aplicação e absorção, sendo os sintomas mais visíveis de dois a quatro dias após a aplicação.

Referente a fertilizantes, analise as assertivas a seguir:
I. A solubilidade dos fertilizantes fosfatados no solo varia em função do tipo de fosfato, do tratamento químico ou térmico da rocha fosfatada.
II. As principais fontes de potássio disponíveis no mercado são o cloreto de potássio, o sulfato de potássio e o carbonato de potássio, sendo este menos reativo em relação aos demais.
III. Superfosfato simples, superfosfato triplo, fosfato monoamônico e fosfato diamônico são exemplos de fosfatos acidulados.
IV. Para ser considerado um fertilizante organomineral, o material precisa apresentar no mínimo 8% de carbono orgânico e CTC mínima de 80 mmolc/kg e umidade de 14% em base seca.

Um dos fatores cruciais para o desenvolvimento de plantas a fim de que elas expressem seu potencial produtivo são as condições de fertilidade que o solo apresenta. Referente ao uso de corretivos de solo, analise as assertivas a seguir, assinalando V, se verdadeiras, ou F, se falsas.
( ) A necessidade de calagem é um parâmetro quantitativo usado para informar a quantidade de calcário a ser aportado ao solo para elevação do pH.
( ) Para elevação do valor de pH de um solo, por exemplo, para 6,0, solo este com índice SMP de 5,0, a quantidade de calcário a ser aportada é de 9,9 t/ha, desde que for PRNT 100%. Para esse caso, quanto mais fino for a moagem da rocha calcária, menor é a quantidade de calcário a ser aplicada e mais rápido será a elevação do pH.
( ) Uma alternativa ao uso do índice SPM é usar a saturação por bases, sem a necessidade de manter a estimativa da acidez potencial via índice SMP, uma vez que ao elevar o pH do solo, a acidez potencial baixa.
( ) Solos com baixo poder tampão, geralmente com índice SMP maior do que 6,3, a recomendação técnica é usar equações polinomiais que levam em conta o teor de matéria orgânica do solo e o alumínio trocável.
( ) Uma vez corrigida a acidez potencial pela calagem, o solo iniciará um processo de reacidificação, sem necessariamente retornar ao mesmo estado de acidez potencial anterior à aplicação de calcário.

O crescimento e desenvolvimento de plantas depende de fatores edafoclimáticos que, se combinados adequadamente dentro de faixas tidas como adequadas, permite que a planta expresse seu potencial produtivo. Referente aos fatores climáticos, analise as assertivas a seguir, assinalando V, se verdadeiras, ou F, se falsas.
( ) O regime térmico de um solo é determinado pelo aquecimento de sua superfície pela radiação solar e transporte de calor sensível ao seu interior, pelo processo de convecção.
( ) A variação da temperatura do solo ao longo do dia e da profundidade no solo pode ser estudada a partir da elaboração e análise de tautócronas de temperatura.
( ) Para fins efetivos de contabilização da quantidade de água que chega até o solo por meio de uma precipitação pluviométrica qualquer, as características do dossel têm pouco ou nenhuma importância no cálculo de recarga hidráulica.
( ) O balanço de radiação ou radiação líquida é composto pelo balanço de ondas longas e curta que chega até a superfície, cuja unidade de medida é megajoule por área-dia.
( ) Os conceitos sobre regime térmico do solo e do ar, balanço de energia, necessidade de disponibilidade de água não se aplicam para ambientes protegidos, pois os conceitos são outros.

Introducing… Roses
01 Roses (Rosa) are a classic and instantly recognizable plant, ideal for almost every style
02 of garden. They flower abundantly from early summer in a choice of colors including pastel
03 shades of pink, peach, cream, or snowy-white; vibrant yellow and gold; orange, crimson or
04 red. Many roses are fragrant. Some types flower in one flush of blooms while others flower
05 all summer long. Some have colorful fruits (hips). Plants come in a range of forms, from
06 traditional shrubs and climbers to miniature plants for patio containers.
07 Roses have upright, arching, scrambling or trailing, usually prickly stems. Their leaves
08 are glossy and mid to dark green but occasionally grey-green. Flowers vary in shape and
09 include flat, cupped, rounded, urn-shaped, button-eye, pompon, and rosette. They grow
10 best in moisture-retentive, fertile, well-drained soils in a sunny position. They are very
11 responsive to mulching and feeding, and they won't thrive in dry, poor or waterlogged soil,
12 and few flowers are produced in shade.
13 There so many different types of roses that the choice can a little
14 overwhelming when you decide to start growing. To narrow down your options, you may
15 consider the type of flower, the size of the plant, and the kind of soil you have. With roses
16 in particular, the flowers themselves often the deciding factor, and it all down to
17 personal taste: do you want the large opulent blooms of an old-fashioned rose or something
18 more delicate and refined such as a Hybrid Tea rose? What color would work well with your
19 other plants? What type of scent do you prefer? Some roses have a fruity fragrance while
20 others have a musk or tea scent.
21 For all of these aspects, but especially fragrance, it’s best to see and smell the
22 fragrance of the plants in bloom before you buy – either at a garden center or nursery, or
23 when visiting gardens where they grow roses in abundance. You will also see the size of a
24 grown plant. Roses can range from compact types for patio containers to huge vigorous
25 ramblers that can grow through the branches of a tree. There are roses to suit almost every
26 planting site, so assess your particular conditions which may be shady, frost-prone, or have
27 a soil that may dry out in summer, then look for a rose that will thrive there.
